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

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

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!

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

Types of catheter
1)Indwelling catheter
• Rubber catheter
• Plastic (PVC)
• Silicone
• Latex-foleys
• Polyurethane
2) External Catheters
• Condom catheter
3) Short term (Intermittent) catheter
• Robinson catheter
• Infant feeding tube( in case of paediatrics)
Catheterization allows the patient's urine to drain freely from the bladder for collection. It
may be used to inject liquids used for treatment or diagnosis of bladder conditions.
5. Indication
- Short term for acute urinary retention:
- Need for immediate and rapid bladder decompression
- Monitoring of intake and output
- Temporary relief of bladder outlet obstruction secondary to:
• Enlarged prostate gland in men
• Urethral stricture
- Chronic urethral obstruction or urinary retention and surgical interventions,
- Short-term following a urological or gynaecological surgical procedure
- Irreversible medical conditions are present (e.g., metastatic terminal disease, coma)
- Presence of stage III or IV pressure ulcers that are not healing because of continual urine leakage
Contra-indication
Pelvic/urethral injury

9. Step 03
• Using an aseptic technique open the catheter pack and pour antiseptic solution into the receiver. Open the rest of
your equipment onto the sterile field.
• Wash and dry your hands, then put on the sterile gloves.
• Open the sterile drapes and place in position
• Cover the area with sterile dressing and minimize the exposure
• Place sterile drape
Step 04
(MALE)
• Hold the penis with your non dominant hand and with the other a sterile swab and clean the penis thoroughly.
• Retract the foreskin and clean around the urethral meatus.
• Hold the penis vertically with one hand and with the other hold the catheter by its sleeve.
• Advance the catheter tip from its sleeve and insert into the urethra.
• Progressively insert the catheter, ensuring that neither your hand nor the sleeve touch the penis until the end arm
reaches the meatus. At this point urine should start to flow into the collecting vessel.
• Inflate the balloon using 10ml of sterile water, ensuring that it does not cause any
9
10. (female)
• With your non dominant hand, part the labia. Using saline soaked gauze balls, clean the
urinary meatus with your right hand. Use single downward movements with each gauze.
• With the labia still parted, and ensuring you identify the meatus, insert the syringe of
lignocaine gel and inject the whole syringe.
• Using your dominant hand only, pick up the catheter by its sleeve and start to insert it into the
meatus. Continuing to use the sleeve, insert the catheter until the end arm reaches the
meatus. At this point, urine should start to flow into the collecting vessel.
• Inflate the balloon using 10ml of sterile water, ensuring that it does not cause any pain.
• Attach the catheter bag.
• Gently pull on the catheter until resistance is felt. This is when the balloon will be resting on
the urethral opening of the bladder.

11. During Procedure
- Urethral strictures/ meatul stenosis in en
- Urethral obstruction in men
Post Procedure
- Catheter related infections
- Paraphimosis
- Urethral injury- due to malposition, traumatic insertion, fase lumen
Post Removal
- UTI
- Urine leakage, incontinence
- Acute urinary retention
- Urethral injury- failed to deflate the balloon completely
- Urethral strictures
Complications
11
12. • Ureteric Catheters small-caliber, flexible, open-tipped catheters that are designed to pass into
ureters- Strictures
• Coude catheters- have a slight bend at the tip, helping to maneuver the catheter beyond
obstructions in the bulbar and prostatic urethra
(by trained UROLOGIST)
• Urethral dilators- graduated plastic or metal rods that can be passed over a wire to dilate the
urethra sequentially.
• Filiforms and followers- Filiforms are small; flexible tubes used to maneuver past strictures and
stenosis.
• Guidewires- are useful in assuring access to the bladder. Such wires are most safely used with the
aid of cystoscopic visualization to confirm passage into the bladder, though the blind passage of soft
wires into the bladder has been described
• Percutaneous Urinary Kit - When access to the bladder via the urethra is not able to be safely
completed, or when a urethral stricture repair is being considered, a suprapubic tube (SPT) may be
placed
Troubleshooting difficult insertions
12
16. • Distorted local anatomy (eg, from vascular injury, prior surgery, or previous irradiation)
• Infection at insertion site
• Presence of anticoagulation or bleeding disorder
• Uncooperative patient
• Vessel thrombosis, stenosis, or disruption
16
18. • IJC 1- central approach: find 1cm above the apex
of head of SCM and clavicle -> 60 degrees to
skin aiming towards ipsilateral nipple (blood
should be obtained within 3cm)
2- lateral/posterior approach: find 2-3 finger
breaths above clavicle along posterior border
of SCM, direct needle towards jugular notch
(blood should be aspirated within 5cm)
3- anterior approach: identify the carotid and
mid point of medial SCM border, aim toward
ipsilateral nipple
18
19. • Subclavian
the junction of the lateral two thirds and the
medial third of the clavicle.
The needle tip should be directed at the
index finger (or just superior to its tip)
19
20. • Femoral
the inguinal ligament and the midpoint of
the femoral arterial pulse.
The femoral vein is medial to the femoral
pulse
The puncture should be approximately 1-
1.5cm medially to the maximal femoral
pulse, and approximately 1cm inferior to
the inguinal ligament
20
24. • An over-wire technique of catheter
insertion to obtain safe percutaneous
access to vessels and hollow organs
• Cardiac ectopy may be induced by a
guidewire or catheter in the right atrium
or ventricle.
• Never lose grasp of the guidewire !
Insert dilator
and remove it
Insert cvl and
remove guidewire 24
28. • For optimal dilution- tip should
be closest to the right ventricle
• Perforation-cardiac tamponade
(deep) haemomediastinum,
thrombosis (high)
• Above the cephalic limit of the
pericardial reflection
• at a level corresponding to the
carina on a chest radiograph

• An assessment to gather all information to optimize comorbidities and then organize
anesthetic, surgical and postoperative care before surgery takes place
• The goal of the evaluation of the healthy patient is to detect unrecognized disease and
risk factors that may increase the risk of surgery above baseline and to propose strategies
to reduce this risk.
• Patients scheduled for elective procedures will generally attend a pre-operative
assessment 2-4 weeks before the date of their surgery.
• Preoperative assessment include
• Pre-Operative History
• Pre-Operative Examination
• Pre-Operative Investigations
57. 57
The pre-operative history follows the
same structure as typical history taking,
with the addition of some anesthetic and
surgery specific topics.
History of Presenting Complaint/ Surgery specific symptoms (including
features not present), onset, duration and exacerbating and relieving factors.
Past Medical History (Cardiovascular, Respiratory, Gastrointestinal,
Neurological, Endocrine, Renal, Pregnancy and Hematological)
Past Surgical history
Past Anesthetic History
Drug History including allergies, both drug and non-drug
Family History
Social History (smoking, alcohol, recreational drugs use)
59. 59
Two distinct examinations are
performed; the general examination (to
identify any underlying undiagnosed
pathology present) and the airway
examination (to predict the difficulty of
airway management e.g. intubation). If
appropriate, the area relevant to the
operation can also be examined.
General Anaemia, jaundice, cyanosis, nutritional status,
sources of infection (teeth, feet, leg ulcers)
Cardiovascular Pulse, blood pressure, heart sounds, bruits,
peripheral oedema
Respiratory Respiratory rate and effort, chest expansion and
percussion note, breath sounds, oxygen saturation
Gastrointestinal Abdominal masses, ascites, bowel sounds, hernia,
genitalia
Neurological Consciousness level, cognitive function,
sensation, muscle power, tone and reflexes
Airway assessment Samsoon and Young modified Mallampati test
Other indicator of difficult airway (loose teeth,
obvious tumors, scars, infections, obesity,
thickness of the neck)
60. 60
A classification system to assess and communicate a patient’s pre-anesthesia medical co-morbidities.
The classification system alone does not predict the perioperative risks, but used with other factors (eg, type of
surgery, frailty, level of deconditioning), it can be helpful in predicting perioperative risks.
ASA PS
Classification
Definition
Adult Examples, Including, but not Limited to: Absolute Mortality (%)
ASA I A normal healthy patient Healthy, non-smoking, no or minimal alcohol use 0.1
ASA II A patient with mild systemic
disease
Mild diseases only without substantive functional limitations. Current smoker, social alcohol drinker,
pregnancy, obesity (30<BMI<40), well-controlled DM/HTN, mild lung disease
0.2
ASA III A patient with severe systemic
disease
Substantive functional limitations; One or more moderate to severe diseases. Poorly controlled DM or HTN,
COPD, morbid obesity (BMI ≥40), active hepatitis, alcohol dependence or abuse, implanted pacemaker,
moderate reduction of ejection fraction, ESRD undergoing regularly scheduled dialysis, history (>3 months) of
MI, CVA, TIA, or CAD/stents.
1.8
ASA IV A patient with severe systemic
disease that is a constant threat
to life
Recent (<3 months) MI, CVA, TIA or CAD/stents, ongoing cardiac ischemia or severe valve dysfunction,

ASA VI A declared brain-dead patient
whose organs are being
removed for donor purposes
-
61. Blood Investigation
61
The nature of the exact investigations required depends on a number of factors, including co-morbidities, age, and
the nature of the procedure.
The urgency of the surgery will also dictate which conditions need further investigation and management prior to
surgery. For example, elective surgery is often delayed for poorly controlled blood glucose levels in diabetic patients,
to allow time for optimisation
Cardiac Investigation
• Full Blood Count (FBC)
• Urea & Electrolyte
• Liver Function Test
• Coagulation Profile
• Condition-specific blood test
• Hba1c
• Thyroid function test
• Group and Save (GSH) +/- cross matching
• Electrocardiogram (ECG)
• Echocardiogram (ECHO)
• Myocardial Perfusion Scan
Respiratory Investigation
• Plain film chest radiograph (CXR)
• Spirometry
Other
• Urinalysis
• Urine Pregnancy Test
62. 62
Many patients undergoing major noncardiac surgery
are at risk for a cardiovascular event. The risk is
related to patient- and surgery-specific
characteristics. Identification of increased risk
provides the patient (and surgeon) with information
that helps them better understand the benefit-to-risk
ratio of a procedure and may lead to interventions
that decrease risk.
63. History/Symptoms
63
Physical Examination
• Angina
• Dyspnoea
• Syncope
• Palpitation
• History of heart disease
• History of Hypertension, CKD, Diabetes,
cerebrovascular or peripheral artery disease
• Cardiovascular examination
• Blood pressure measurement
• Auscultation of heart and lung
• Examination of extremities for oedema
Electrocardiogram (ECG)
• The rationale for obtaining a preoperative ECG comes from the
utility of having a baseline ECG should a postoperative ECG be
abnormal.
• Preoperative ECG should be evaluated for the presence of Q
waves or significant ST-segment elevation or depression, which
raises the possibility of myocardial ischemia or infarction, left
ventricular hypertrophy, QTc prolongation, bundle-branch block, or
arrhythmia
Functional status/capacity
• Cardiac functional status or capacity, as determined by doctors
assessing patients with a brief set of questions, has been thought
to be positively associated with postoperative outcomes.
• Functional status can be expressed in metabolic equivalents (1
MET is defined as 3.5 mL O2 uptake/kg per min, which is the
resting oxygen uptake in a sitting position).
• The ability to achieve four METs of activity without symptoms is
thought to be a good prognostic indicator
Can take care of self, such as eat, dress, or
use the toilet (1 MET)

• All patients scheduled to undergo noncardiac surgery should have an initial assessment of the risk (in percent)
of a cardiovascular perioperative cardiac event using validated models that typically include information from the
history, physical examination, electrocardiogram, and type of surgery.
• The purpose of this assessment is to help the patient and health care providers weigh the benefits and risks of
the surgery and optimize the timing of the surgery.
• There few model for cardiac risk assessment
• Revised Cardiac Risk Index (RCRI), also referred to as the Lee index
• American College of Surgeons surgical risk calculator (ACS-SRC)
• Myocardial Infarction or Cardiac Arrest (MICA) calculator (derived from National Surgical Quality Improvement
Program (NSQIP) database)
• AUB-POCES index (renamed AUB-HAS2)
• VSGNE risk index
68. • Medicine that help prevent blood clots, reducing fibrin formation and preventing clots from forming
and growing
• Given to people at high risk of getting clots to reduce risk of strokes and heart attack
Types of anticoagulant
• Warfarin (commonest) – maximum effect at 48 hours after administration and last for next five days
• Heparin – half life about 1 hour
• Rivaroxaban (Xarelto)
• Dabigatran (Pradaxa)
• Apixaban (Eliquis)
• Edoxaban (Lixiana)
68
69. • Decrease platelet aggregation and inhibit thrombus formation
• Interfere with platelet activation in primary hemostasis
• Effective in the arterial circulation in which anticoagulants have little effect
Types of antiplatelet
• Aspirin (half life is 20 minutes, however duration of life is 10 days)
• Clopidogrel (Plavix)
• Prasugrel (Effient)
• Ticagrelor (Brillinta)
69
71. Heparin can be ceased for a short time in perioperative period
- Withhold an infusion for 4 hours before surgery
- Recommence once the risk of postoperative bleeding is low
Subcutaneously administered heparin or enoxaparin (Clexane) is withheld the day or evening before the surgery
- Recommence once patient can take oral medication
Rapid reversal of warfarin prior to an emergency operation may be achieved with Vitamin K, pooled fresh frozen
plasma or clotting factors
71
72. • Difficult to reverse acutely
• Need to be ceased 2-5 days preoperatively
• A specific dabigatran reversal agent has recently been released (idarucizumab (praxbind))
72
73. The American College of Chest Physicians recommend that if annual risk for thromboembolism is low, warfarin can
be withheld for 4-5 days before procedure without bridging
73
74. Patients with mechanical heart valve or AF or VTE
- At high risk for thromboembolism
Bridging anticoagulant is recommended with therapeutic-dose subcutaneous LMWH
- At moderate risk for thromboembolism
Base the plan for bridging vs no bridging on the individual patient rather than a generalized
consensus. The bridging anticoagulation can be done with therapeutic-dose SC LMWH,
therapeutic-dose IV UFH or low-dose SC LMWH based on the patient
- At low risk for thromboembolism
Low-dose SC LMWH is recommended
74
76. • The antiplatelet agents (aspirin,clopidogrel, or ticagrelor) taken alone
or in combination should be ceased at least 5 days prior to an
operation
• Bleeding will be highly problematic at the time of surgery especially if
multiple antiplatelets agents are continued
• Combined usage often follows coronary artery stenting and so their
withdrawal in context of surgery should be discussed with
interventional cardiologist
76
78. • Bridging therapy low molecular weight heparin, similar to what is recommended for
patients on warfarin, has been considered.
• However, heparin has relatively minor effects on platelets, and thus does not prevent a
thrombotic event.
• Therefore, despite being recommended as an alternative therapy by several societies, it
does not seem to be an appropriate choice.
• Alternatively, bridging with short-acting GP IIb/IIIa inhibitors (tirofiban and eptifibatide) can
be considered
• Society of Thoracic Surgeons, ESC and Australia/ New Zealand guidelines recommend
such an approach in patients at high risk of cardiovascular events
78
80. • Post-operative complications may either be general or specific to the
type of surgery undertaken
• the management provided should consider the type of surgery, patient’s
needs and medical history
80
81. Common:
• Post-operative fever
• Respiratory complication- Atelectasis
• Wound infection
• Embolism
• Deep vein thrombosis
Immediate
• Primary haemorrhage: either starting during surgery or following post-operative increase
in blood pressure
• Basal atelectasis: minor lung collapse
• Shock: blood loss,acute myocardial infarction, pulmonary embolism or septicaemia.
• Low urine output: inadequate fluid replacement intra- and post-operatively.
81
82. • Acute confusion: exclude dehydration and sepsis
• Nausea and vomiting: analgesia or anesthetic-related, paralytic ileus
• Pyrexia
• Secondary haemorrhage: often as a result of infection
• Pneumonia
• Wound or anastomosis dehiscence
• Deep vein thrombosis (DVT)
• Acute urinary retention
• Urinary tract infection (UTI)
• Post-operative wound infection
• Bowel obstruction due to fibrinous adhesions
• Paralytic Ileus
82
83. • Bowel obstruction due to fibrous adhesions
• Incisional hernia
• Persistent sinus
83
84. Causes
• The Five “W”
• Wind (POD#1) Atelectasis, pneumonia
• Water (POD#3) UTI, anastomotic leak
• Wound (POD#5) Wound infection, abscess
• Walking (POD#7) DVT / PE
• What we give/do?
• Blood transfusions, central lines we put in (line sepsis)?? Operation related??
• Another W What can kill?
• necrotising fasciitis, malignant hypoerhermia, allergic reaction/transfusion
84
85. Early (Day 1-3)
Mild fever - Temperature <38°C (common)
• Tissue damaged and/or necrosis at the op-site
• Haematoma
Persistent fever – Temperature >38°C
• Atelectasis: collapsed lung may become secondarily infected
• Specific infections post surgery
• Blood transfusion or drug reaction
85
86. • Attend to the patient, assess clinically
• History
• Examination
• Temperature
• Look for sign to rule out each causes
• Investigations
• Septic workout
• U/S Doppler if indicated
• Management
• Manage the cause involved – antipyretic, sponging, IV fluid resuscitation
86
90. • Type – concealed/open
• Factor
a. Local – infection, ischemia
b. Suture – poor handling, material, tight closure
c. Systemic – age, nutrition, DM
• Management
a. Superficial – release suture, drain pus/haematoma
b. Burst abdomen – cover gut, early abdominal wall closure, tension suture
c. Concealed Dehiscence – incisional hernia repair, mesh repair, abdominal corset
90
91. May be resulted from:
• Ineffective local hemostasis
• Complications of blood transfusion
• Undetected hemostatic defect
• Consumptive coagulopathy and/or fibrinolysis
Perioperative Hemorrhage:
• Primary – bleeding that occurs within intra-operative period
• Reactive – occurs within 24 hours of operation
• Secondary – occurs 7-10 days post opratively
