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!

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.

Image receptor: 24 x 30 cm crosswise
Position at patient: Examine the patient in the upright or
the supine position
• NOTE: Do not have the patient rotate the arm if
fracture or dislocation is suspected.
Position of part :
• Center the shoulder joint to the midline of the grid.
• Adjust the position of the IR so that its center is I inch
(2.5 cm) inferior to the coracoid process.
5. • If necessary to overcome the curve of the back and the
resultant obliquity of the shoulder structures, slightly
rotate the patient enough to place the body of the
scapula parallel with the plane of the IR.
Central ray : Perpendicular to a point I inch (2.5 cm)
inferior to the coracoid process.
Respiration: Suspend.
Shoulder
7. External Rotation Humerus
• Ask the patient to supinate the hand, unless
contraindicated .
• Abduct the arm slightly, and rotate it so that the
epicondyles are parallel with the plane of the IR.
• Externally rotating the entire arm from the neutral
position places the shoulder and entire humerus in the
true anatomic position.
The greater tubercle of the humerus and the site of
insertion of the supraspinatus tendon are visualized.
Shoulder
8. Neutral Rotation Humerus
• Ask the patient to rest the palm of the hand against the
thigh . This position of the arm rolls the humerus slightly
internal into a neutral position. placing the epicondyles
at an angle of about 45 degrees with the plane of the IR.
The posterior part of the supraspinatus insertion, which
sometimes profiles small calcific deposits not otherwise
visualized

9. Internal Rotation Humerus
• Ask the patient to flex the elbow somewhat, rotate the
arm internally. and rest the back of the hand on the hip.
Adjust the arm to place the epicondyles perpendicular to
the plane of the IR.
The proximal humerus is seen in a true lateral position.
When the arm can be abducted enough to clear the
lesser tubercle of the head of the scapula, a profile
image of the site of the insertion of the subscapular
tendon is seen.

TRANSTHORACIC LATERAL PROJECTION
(R or L position) LAWRENCE METHOD
Image receptor: 24 x 30 cm lengthwise
Position at patient:
• For upright positioning. seat or stand the patient in the
lateral position before a vertical grid device. If an
upright position is not possible.
• place the patient in a recumbent position on the table
with radiolucent pads elevating the head and shoulders.
11. • Have the patient raise the uninjured arm, rest the
forearm on the head. And elevate the shoulder as much
as possible.
• Center the IR to the surgical neck area of the affected
humerus.
Respiration: Full inspiration.
Having the lungs full of air improves the contrast and
decreases the exposure necessary to penetrate the body.
A minimum exposure time of 3 seconds (4 to 5 seconds is
desirable) will give excellent results when a low
milliamperage is used
Shoulder
12. Central ray : Perpendicular to the IR. entering the
midcoronal plane at the level of the surgical neck. If the
patient cannot elevate the unaffected shoulder. angle the
central ray 10 to 15 degrees cephalad to obtain a

20. PA OBLIQUE PROJECTION
(RAO or LAO position) Scapular Y
Image receptor: (24 x 30 cm)
• This projection, described by Rubin, Gray, and Green, I
obtained its name as a result of the appearance of the
scapula.
• The body of the scapula forms the vertical component of
the Y, and the acromion and coracoid processes form
the upper limbs.
• The projection is useful in the evaluation of suspected
shoulder dislocations.

PEARSON METHOD
Image receptor : 18 x 43 cm or two 8 X 10 inch (18 x 24
cm), as needed to fit the patient
SID: 72 inches (183 cm). A longer SID reduces
magnification, which enables both joints to be included
on one image.
• It also reduces the distortion of the joint space resulting
from central ray divergence.
Position of patient : Achieve this position with the patient
seated or upright.
37. • Center the midline of the body to the midline of the grid.
• Ensure that the weight of the body is equally distributed
on the feet to avoid rotation.
• With the patient's arms hanging by the sides, adjust the
shoulders to lie in the same horizontal plane.
• It is important that the arms hang unsupported.
Make two exposures:
• one in which the patient is standing upright without
weights attached, and a second in which the patient has
equal weights (5 to 8 Ib) affixed to each wrist

more uniform density image.
Central ray : Perpendicular to the mid shaft of the
clavicle.
Clavicle
48. PA PROJECTION
The PA projection is generally well accepted by the patient
who is able to stand, and it is most useful when
improved recorded detail is desired. The advantage of
the PA projection is that the clavicle is closer to the
image receptor, thus reducing the OlD.
Positioning is similar to that of the AP projection. The
differences are as follows:
• The patient is standing upright (back toward the x-ray
tube) or prone .
• The perpendicular central ray exits midshaft of the
clavicle .
• Structures shown and evaluation criteria are the same
as for the AP projection.

• Position of patient : Stand or seat the patient I foot in
front of the vertical IR device, with the patient facing the
x-ray tube.
• Alternatively, if the patient is unable to stand and
assume the lordotic position, place the patient supine on
the table
51. Position of part :
(Standing lordotic position )
• Have the patient lean backward in a position of extreme
lordosis, and rest the neck and shoulder against the
vertical grid device.
• The neck will be in extreme flexion. Center the clavicle

53. Central ray :
Directed to enter the midshaft of the clavicle.
• For the standing lordotic position, 0 to 15 degrees is
recommended.
• For the supine position, 15 to 30 degrees is
recommended
Thinner patients require more angulation to project the
clavicle off the scapula and ribs.
Clavicle
54. PA AXIAL PROJECTION
• Positioning of the PA axial clavicle is similar to the AP
axial projection just described. The differences are as
follows:
• The patient is prone or standing, facing the vertical grid
device.
• The central ray is angled 15 to 30 degrees caudal .

Positionof part :
• If possible, depress the shoulder to place the clavicle in
a horizontal plane .
• Have the patient turn the head away from the side being
examined.
• Place the IR on edge at the top of the shoulder and
support it in position.
56. • The IR should be as close to the neck as possible .
Respiration: Suspend.
Central ray :
• Angled so that the central ray will pass between the
clavicle and the chest wall, perpendicular to the plane of
the IR.
• The angulation will be about 25 to 40 degrees from the
horizontal. If the medial third of the clavicle is in
question, it is also necessary to angle the central ray
laterally; 15 to 25 degrees is usually sufficient.

folded pillow or blankets may be placed on the patient's
lap to support the horizontally placed IR if needed.
• Using the collimator light as the indicator, center the IR
to the projected clavicle area, and have the patient hold
the IR in position.
59. • Ask the patient to lean slightly forward
Respiration: Suspend.
Central ray :
• Directed anterior and inferior to the midshaft of the
clavicle at a 25- to 35-degree angle. It should pass
perpendicular to the longitudinal axis of the clavicle.
• Because of the considerable OlD, an increased SID is
recommended to reduce magnificat
