Colles fracture is the fracture at the distal end of radius, at its
cortico cancellous junction(about 2cm from the distal articular
surface).
It is not just the fracture of distal radius but the fracture
dislocation of the inferior radio-ulnar joint.

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.
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
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!
1. Carpal Tunnel Syndrome
INSTRUCTION
Examine this patient's hands.
SALIENT FEATURES
History
· Ask the patient about nocturnal pain (commonest cause of hand pain at night).
· History of oral contraceptives, rheumatoid arthritis, myxoedema, acromegaly,
chronic renal failure, sarcoidosis.
· Take a family history (abnormally small size of carpal tunnel runs in families).
Examination
· Wasting of the thenar eminence.
· Weakness of flexion, abduction and opposition of thumb.
· Diminished sensation over lateral three and half fingers.
Proceed as follows:
· Look carefully for scar of previous surgery (hidden by the crease of the wrist).
· Percuss over the course of the median nerve in the forearm: patient may
experience tingling - this is Tinel's sign.
· Ask the patient to hyperextend the wrist maximally for 1 minute; this may bring on
symptoms (dysaesthesia over the thumb and lateral two and half fingers).
· Tell the examiner that you would like to:
-Examine for underlying causes such as myxoedema, acromegaly and rheumatoid
arthritis.
Look for cervical spondylosis, frozen shoulder and tennis elbow (these may be
associated).
-Look for the Cimino-Brescia fistula for haemodialysis
“Sir, my patient is a middle age lady who appears well. On inspection, both of her
hands are in the normal resting position with the forearm supinated and wrist
extended. The MCP and IP joints are flexed, more pronounced in the little finger and
less in the index finger.
I also notice wasting of the thenar eminence of the left hand; in addition, there is a
3cm scar over the transverse carpal ligament of the right hand signifying possible
previous carpal tunnel release of the right hand.
Abduction of the left thumb is weak, power is grade 3, but power of the long flexors
of the thumb and index finger was full on testing the flexion of the DIP joint of the
index finger. Sensation is intact but decreased over the radial 3 ½ digits of the left
palm.
Tinel’s sign is positive over the ventral aspect of the proximal wrist. Phalen test is
positive and patient reported tingling/numbness along the median nerve distribution.
Functionally, she has a weak power grip, pincer grip, unable to button unbutton shirt,
find it difficult to hold a pen & write.
2. In regards to the etiology of this condition, I was unable to note any evidence of
acromegaly, myxodema, deforming arthropathy (RA), cutaneous stigmata of
pregnancy/abdomen distension, or trauma.
My diagnosis is severe left median nerve palsy secondary to carpal tunnel syndrome.
To complete my examination, I would like to examine for cervical spondylosis which
could have resulted in radiculopathy that may mimic CTS.”
DIAGNOSIS
This patient has median nerve involvement of the hand with Tinel's sign (lesion) due
to carpal tunnel syndrome as a complication of chronic haemodialysis (aetiology).
The patient has disabling tingling and pain at night (functional status).
QUESTIONS
What is carpal tunnel?
Carpal tunnel is a fibro-osseous tunnel situated on the flexor aspect of the proximal
part of the hand and lying between the flexor retinaculum and the carpal bones.
Compression of the median nerve within the carpal tunnel is known as carpal tunnel
syndrome.
What does the carpal tunnel contain?
It contain the median nerve and 10 flexor tendons that include:
(a) 4 tendons of flexor digitorum superficialis.
(b) 4 tendons of flexor digitorum profundus.
(c) Flexor pollicis longus tendon.
(d) Flexor carpi radialis tendon.
Where does the flexor retinaculum attach?
It attach to the tubercle of the scaphoid and pisiform proximally and the hook of the
hamate and trapezium distally. Its function is to prevent bow-stringing of the flexor
tendons at the wrist.
3. What is positive phalen test?
Patient when ask to hold their wrist in complete and forced flexion reports
tingling/numbness along the median nerve distribution in less than 60 seconds.
What muscle does the median nerve innervate in the hand?
It supply 4 muscles in the hand, mnemonic LOAF :
Lateral 2 lumbricals, Opponens pollicis, Abductor pollicis brevis, Flexor pollicis brevis.
Would you expect numbness over the thenar eminence in carpal tunnel syndrome?
No, because the palmar cutaneous branch of median nerve is given off 5cm proximal
to the wrist and then passes superficial to the carpal tunnel.
How would you treat this condition?
Diuretics, wrist splint & Ultrasound treatment, local steroid injection, surgical
decompression (open or endoscopic).
How would you confirm your diagnosis?
Nerve conduction study will show impaired median nerve conduction across the
carpal tunnel in the context of normal conduction elsewhere. Nerve compression
results in damage to the myelin sheath and manifests as delayed distal latencies and
slowed conduction velocities. With sustained or more severe compression, axon loss
may also occur, resulting in a reduction of the median nerve compound motor or
sensory action potential amplitude.
What is Phalen’s test?
Patient is asked to keep both wrist in complete palmar flexion for 1 minute, this
produces numbness or tingling in the distribution of the median nerve.
What are the causes of median nerve neuropathy in the axilla and upper arm?
Axilla : Compression by crutches, sleep palsy, missile & stab injuries, anterior
shoulder dislocation, fascial sheath hemorrhage, false aneurysm.
Upper arm : Arteriovenous fistulas, stab wounds, fractures of the humerus,
tourniquets, sleep palsy.
Mention a few causes of carpal tunnel syndrome.
MEDIAN TRAP:
Myxoedema
Edema premenstrually
Diabetes
Idiopathic
Agromegaly
Neoplasm
Trauma
Rheumatoid arthritis
Amyloidosis
Pregnancy
4. Oral contraceptives.
In chronic renal failure patients on long-term dialysis it is due to [β2-microglobulin as
amyloid deposition.
Amyloidosis (e.g. due to multiple myeloma).
Sarcoidosis.
Hyperparathyroidism.
How would you treat this condition?
1. Diuretics.
2. Wrist splint and ultrasound treatment
3. Local steroid injection should be given proximal to the carpal tunnel (not into
the tunnel because it may damage the nerve)
4. Surgical decompression.
ADVANCED-LEVEL QUESTIONS
How would you confirm the diagnosis?
Nerve conduction studies (increased latency at the wrist on stimulation of the
median nerve; the muscle action potential from abductor pollicis brevis is a valuable
diagnostic sign). Rarely, the proximal latency may be normal with a prolonged distal
latency due to an anastomosis between the ulnar and median nerves in the forearm.
A negative test thus does not rule the syndrome out
absolutely but calls it into question.
Mention a few clinical diagnostic tests
· Wrist extension test: the patient is asked to extend his wrists for I minute; this
should produce numbness or tingling in the
distribution of the median nerve.
· Phalen's test: the patient is asked to keep both hands with the wrist in complete
palmar flexion for I minute; this produces
numbness or tingling in the distribution of the median nerve.
· Tourniquet test: the symptoms are produced when the blood pressure cuff is
inflated above the systolic pressure.
· Pressure test: if pressure is placed where the median nerve leaves the carpal tunnel,
it causes pain.
· Luthy's sign: if the skinfold between the thumb and index finger does not close
tightly around a bottle or cup because of thumb
abduction paresis, this test is regarded as positive.
· Durkan's test: direct pressure over the carpal tunnel - the carpal compression test is more sensitive and specific than the Tinel
and Phalen sign.
Mention other entrapment neuropathies.
· Meralgia paraesthetica (lateral cutaneous nerve of the thigh trapped under the
inguinal ligament).
· Elbow tunnel syndrome (ulnar nerve trapped in the cubital tunnel)
· Common peroneal nerve trapped at the head of the fibula
5. · Morton's metatarsalgia (trapped medial and lateral plantar nerves causing pain
between third and fourth toes).
· Tarsal tunnel syndrome (posterior tibial nerve is trapped).
· Suprascapular nerve trapped in the spinoglenoid notch.
· Radial nerve trapped in the humeral groove.
· Anterior interosseous nerve trapped between the heads of the pronator muscle.
Carpal tunnel release
Positioning: Supine with side arm table, palm upright.
Prep: Betadine scrub, then paint (or chloroprep)
Incision:
Identify landmarks: distal crease (stay above this), in line with palmaris longus
tendon and web space (3&4).
Draw plumb line from 3rd – 4th interspace down through midline of palm.
Incision will be on the ulnar side of the midline palmar crease. Stay under cardinal
line and above distal crease.
Procedure:
Infiltrate local anesthetic
Incise using 15 blade, cut 3-4 cm.
Cut down with 15 blade to palmar aponeurosis and open sharply.
Place Intern retractor.
Continue with 15 blade to Transverse Carpal Ligament (TCL), cut through it layer by
layer.
Using Penfield 4 to dissect the space above the nerve and TCL.
Open the remaining portion of the TCL distally into the wrist using scissors. Once
fully opened, the Penfield 4 will pass freely into the wrist.
Closure:
Close palmar aponeurosis using 4-0 vicryl.
Close dermis/fat with 4-0 vicryl, then 3-0 nylon running for skin.
Cover with Xeroform over the incision, then fluffs in palm. Wrap with Kerlix and
loose Ace wrap in slight extension. May remove in 3 days (typically).
