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
ARTIFICIAL INTELLIGENCE IN HEALTHCARE.pdfAnujkumaranit
Artificial intelligence (AI) refers to the simulation of human intelligence processes by machines, especially computer systems. It encompasses tasks such as learning, reasoning, problem-solving, perception, and language understanding. AI technologies are revolutionizing various fields, from healthcare to finance, by enabling machines to perform tasks that typically require human intelligence.
Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

Presenter: Dr. Faiza, Assistant Professor of Physiology
Qualifications:
MBBS (Best Graduate, AIMC Lahore)
FCPS Physiology
ICMT, CHPE, DHPE (STMU)
MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path
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.

1. Neonatal Resuscitation
P a g e | 1

Immediate Care of Newborn in Delivery Room
(Neonatal Resuscitation)
General considerations:
- Alveoli are filled with lung fluid.
- Fetus is dependent on placenta for gas exchange.
- The pulmonary arterioles are constricted.
- The pulmonary blood flow is decreased.
- Blood flow is directed across ductusarteriosus.
Changes from fetal to neonatal circulation: (Transition at birth)
1. Fetal lung fluid leaves the alveoli.
2. Secretion of surfactant.
3. Inflation of the lungs i.e. lungs expand with air.
4. The pulmonary arterioles dilate.
5. The pulmonary blood flow increases.
6. Blood O2 level rises.
7. Ductus arteriosus constricts.
8. Blood flows through lungs to pick up O2.
- Lack of lung ventilation results in:
1. Hypercapnia, hypoxia & metabolic acidosis.
2. Sustained VC of pulmonary arterioles "preventing systemic arterial blood from being oxygenated".
3. Ductus arteriosus remains patent.
4. Lack of adequate oxygenation of the baby`s organs → organ damage (esp. brain) ordeath.
- Successful resuscitation depends on anticipating & immediately recognizing infants
who are need of resuscitation.

1. Asphyxia may be initiated in-utero due to problems in mother, placenta or fetus.
2. Intrauterine asphyxia may extend to the immediate neonatal period by preventing
normal transition.
3. Asphyxia may also be neonatal in origin due to number of problemsincluding
depression by drugs.
1. When a newborn first becomes deprived of O2, an initial period of attempted rapid
breathing is followed by primary apnea & dropping HR that will improve with tactile
stimulation.
2. If O2 deprivation continues → secondary apnea → continuous ↓ in HR & blood pressure.
Secondary apnea cannot be reversed with stimulation; assisted ventilation must beprovided.
1. More difficult resuscitation.
2. Brain damage may occur.
1. Most newborn infants will respond to the stimulation of the extrauterine environmentwith:
- strong inspiratory efforts.
- a vigorous cry.
- movement of all extremities.
2. If these responses are intact:
- color improves steadily from cyanotic or dusky to pink, and
- heart rate becomes adequate.
3. The infant who responds vigorously to the extrauterine environment and who is full
term can remain with the mother to receive routine care (warmth, clearing the
airway, drying)
Causes of asphyxia:
Primary & Secondary apnea:
Consequences of delayed resuscitation efforts:
Normal response to extrauterine environment:

1. Poor muscle tone.
2. Depressed respiratory drive.
3. Bradycardia.
4. Low blood pressure.
5. Cyanosis.
(Personnel and equipment):
1. Every delivery should be attended by at least 1 person whose only responsibility is the baby
and who have the skills required to perform a complete resuscitation.
2. Additional personnel should be present in the delivery room before the delivery occurs.
3. A qualified team with full resuscitation skills, including endotracheal intubation, chest
compressions,emergencyvascularaccess,andmedicationadministration,shouldbeidentified
and immediately available for every resuscitation.
-This team should be present at the birth if the need for extensive resuscitation measures is
anticipated.
4. Prepare necessary equipment: laryngoscope, ambo bag, different sized endotracheal tubes,
suction catheters, umbilical catheters, epinephrine…
5. Check resuscitation equipment ( must be readily available and functional )
6. Use an organized equipment checklist that becomes a routine before every birth.
7. Turn on radiant warmer.
1. Most newly born babies are vigorous.
2. All newborns require initial assessment to determine whether resuscitation is required
3. Only about 10% require some kind of assistance
4. Only 1% needs major resuscitative measures (intubation, chest compressions,and/or
medications) to survive.
5. Unlike adults, who experience cardiac arrest due to trauma or heart disease,
newborn resuscitation is usually the result of respiratory failure, either before or
after birth.
6. Many, but not all, babies who will require neonatal resuscitation can be identified by
the presence of perinatal risk factors.
7. Teamwork, leadership, and communication are critical to successful resuscitation of
the newborn

1. All newborns require initial assessment to determine whether resuscitation is required.
2. The following questions should be asked:
A) If the answer to all of these questions is “Yes”:
- The baby does not need resuscitation
- Infant stay with mother for routine care : ( Warm and maintain normal
temperature , position airway , clear secretions if needed , dry )
- Ongoing evaluation
B) If the answer to any of these assessment questions is “No”:
- Resuscitation should be startedrapidly.
- You have approximately 30 seconds to achieve a response from one step before
deciding whether you need to go on to the next.
- Evaluation & decision making are based primarily on respirations, heart rate, and color.
- Clamping the umbilical cord should be delayed for at least 30 to 60 seconds for most
vigorous newborns not requiring resuscitation.
- A vigorous term newborn may have the initial steps of newborn care performed on the
mother's chest or in her arms.
A. Initial steps:
1. Provide warmth.
2. Positioning of the head and neck
3. Clear secretions from the airway if needed
4. Dry
5. Stimulate the baby to breathe
Steps of resuscitation:
1. Term gestation?
2. Breathing or crying?
3. Good muscle tone?
8. Neonatal Resuscitation
P a g e | 8

I. Provide warmth: achieved via:
- Place the baby on a warm surface under a radiant heater.
II. Position the head and neck: achieved via:
Sniffing position: positioning on back with slightly extending neck
"to align posterior pharynx, larynx & trachea".
III. Clear the airway if necessary
▪ Suction the Mouth then the Nose ("M" before "N").
▪ Brief, gentle suctioning is usually adequate.
IV. Dry thoroughly & remove wet towels. ( Especially Head )
V. Stimulate the baby to breathe:
- Appropriate forms of tactile stimulation are:
1- Slapping or flicking the soles of the feet.
2- Gently rubbing the back.
-Use pulse oximetry and the target oxygen saturation
table (Table) to guide oxygen therapy when
resuscitation is anticipated, to confirm your
perception of persistent central cyanosis, if you
give supplemental oxygen, or if PPV is required.
* Visual assessment of cyanosis is not reliable.
-A healthy newborn breathing room air may take
more than 10 minutes to achieve oxygen
saturation greater than 90%.
-CPAP may be helpful if the baby is breathing and the HR < 100 bpm,
but respirations are labored or the oxygen saturation remains below the target.
Targeted preductal SpO2
After birth
1 min 60 % - 65 %
2 min 65 % - 70 %
3 min 70 % - 75 %
4 min 75 % - 80 %
5 min 80 % - 85 %
10 min 85 % - 95 %
- To determine heart rate, listen with a stethoscope, count the number of beats in 6 seconds,
and multiply the number of beats by 10.
- If the heart rate cannot be determined by listening with a stethoscope and the baby is not
vigorous, use an electronic monitor such as a pulse oximeter or an electronic cardiac (ECG)
monitor.

- Strong respiratory effort.
- Good muscle tone.
- Heart rate > 100/min
B. If meconium is present:
- Evaluate respiratory effort, heart rate & muscle tone.
1. If the newborn is vigorous →
- Use a bulb syringe to clear the mouth& nose.
- The baby may remain with the mother for the initial steps.
2. If the newborn is not vigorous →
- bring the baby to the radiant warmer to perform the initial steps.
Note : Routine intubation for tracheal suction is NOT suggested.
If suctioning of meconium is required due to thick secretions obstructing the airways,
Insert endotracheal tube into trachea then attach endotracheal tube to meconium
aspirator which is connected to suction source and apply suction as tube is withdrawn.
Repeat as necessary.
C. Evaluation after 30 seconds :
After the initial steps are completed, further decisions are based on assessment of:
Free-flow o2
- If baby is breathing & HR >100 BUT labored breathing or cyanotic & given by :
1- O2 mask held firmly over baby’s face.
2- O2 tubing cupped closely over the baby’s mouth & nose.
3- Mask from flow-inflating bag ( NOT self-inflating )
- Absent respiratory effort.
- Absent muscle tone.
- Heart rate < 100/min
1. Respiration.
2. Heart rate.
3. Preductal saturation "via pulse oximetry".
10. Neonatal Resuscitation

Neonatology 2018
Kareem Alnakeeb
Positive-pressure ventilation (PPV)
- Ventilation of lung is the single most important & most effective step in compromised
newborns.
- After completing the initial steps, PPV is indicated if:
- PPV is performed using :
1. a resuscitation self-inflating bag with a reservoir (Bag and mask, Ambu bag)
2. flow inflating bag, or
3. T-piece resuscitator (Neopuff).
- General criteria of a self inflating bag:
T -piece resuscitators (Neopuff )
1) Require a compressed gas source.
2) Use adjustable dials to select the PIP and PEEP.
3) Can be used to administer free-flow oxygen through the mask.
4) Can be used to administer CPAP to a spontaneously breathing baby.
1- The baby is not breathing (Apnea), or If the baby is gasping, or
2- If the baby's HR < 100 bpm.
3- If the baby is breathing & HR ≥ 100 bpm, but the baby's oxygen saturation cannot
be maintained within the target range despite free-flow oxygen or CPAP.
1. Appropriate-sized mask
(cushioned, anatomically shaped mask is preferred).
2. Size of bag: 200-750 ml
3. Safety features (pop-off valve & pressure manometer) to prevent high pressure delivery
4. Always refills after being squeezed.
5. Cannot be used to administer free-flow oxygen through the mask.
6. Cannot be used to administer CPAP to a spontaneously breathing baby
7. An oxygen reservoir must be attached to deliver high concentrations of oxygen (90-100%)
using a self inflating bag.
8. Without reservoir, the bag delivers only about 40% oxygen which may be insufficient for
neonatal resuscitation.

• The desired PEEP is set by adjusting the T-piece aperture
• The desired PIP is set by turning the inspiratory pressure control

- Once PPV starts, at least 2 qualified providers are needed to perform all of the steps efficiently.
- Place yourself at baby’s side or head & Select correct mask that cover tip of chin, mouth & nose
- During PPV,
First assessment
- Check the heart rate after the first 15 seconds of PPV.
- If HR is not increasing within the first 15 seconds of PPV, check for chest movement.
- If HR is not increasing within the first 15 seconds of PPV & you do not observe
chest movement, start the ventilation corrective steps.
* The 6 ventilation corrective steps (MR. SOPA) are:
Second assessment
- Check HR again after 30 seconds of PPV that inflates the lungs (moves the chest).
A) If HR is at least 100 bpm → gradually reduce the rate & pressure of PPV
while observing for effective spontaneous respirations and stimulating
thebaby.
✓ PPV may be discontinued when the HR is continuously > 100 bpm and
the baby has sustained spontaneous breathing.
✓ After PPV is discontinued, use free-flow oxygen or CPAP as
necessary (to maintain the O2 saturation within the target range).
- The initial O2 concentration for newborns ≥ 35 weeks' gestation is 21 %. (Room air)
- The initial O2 concentration for newborns < 35 weeks' gestation is 21 % - 30%.
- During resuscitation, breaths should be delivered at a rate of 40 to 60 breaths per minute
(breath, two, three...breath, two, three).
- The initial ventilation pressure is 20 - 25 cm H2O.
- The most important indicator of successful PPV is a rising heart rate.
M: Mask adjustment
R: Reposition the head
S: Suction mouth & nose
O: Open the mouth
P: Pressure increase (5-10 cm H2O increments) to maximum 40 cm H2O
A: Alternative airway (endotracheal tube or laryngeal mask)

B) If HR is at least 60 bpm, but < 100 bpm and not improving despite 30 seconds of
PPV that inflates the lungs (chest movement),
C) If HR remains < 60 bpm despite at least 30 seconds of PPV that inflates the
lungs (chest movement),
If no improvement, increase O2 concentration (FiO2) to 100% & begin chest compressions.
- reassess your ventilation technique,
- perform the ventilation corrective steps if necessary,
- adjust the oxygen concentration as indicated by pulse oximetry,
- consider inserting an alternative airway if not already done,and
- call for additional expertise.
- reassess your ventilation technique,
- perform the ventilation corrective steps if necessary,
- adjust the oxygen concentration as indicated by pulse oximetry,
- Inserting of an alternative airway (endotracheal tube) is strongly recommended,
- call for additional help.
• If you must continue CPAP or PPV with a mask for more than several minutes, an orogastric
tube should be inserted to act as a vent for the gas in the stomach during the remainder of
the resuscitation.
• To insert an orogastric tube, measure the distance from the bridge of the nose to the
earlobe and from the earlobe to a point halfway between the xiphoid process (the lower
tip of the sternum) and the umbilicus.

Indication
Effect
Positioning of Thumbs or Fingers
Endotracheal intubation
A person experienced in endotracheal intubation should be immediately available to
assist at every delivery.
- Endotracheal intubation may be performed at various points during resuscitation.
- The Intubation procedure should be completed within 20 seconds Using Non-cuffed tube
Indications:
a. If PPV with a face mask does not result in clinical improvement.
b. If PPV lasts > few minutes.
c. If chest compressions arenecessary.
d. In special circumstances, suchas:
(1) Stabilization of a newborn with a suspected diaphragmatic hernia
(2) For surfactant administration,and
(3) For direct tracheal suction if the airway is obstructed by thick secretions.
(4) For epinephrine administration while IV access is being established
Chest compressions
- One person compress chest & another one continues ventilation
when the heart rate remains less than 60 beats per minute despite 30
seconds of effective positive-pressure ventilation (moves the chest).
:
1. Compress the heart against the spine.
2. ↑ intrathoracic pressure.
3. Circulate blood to vital organs "including the brain".
1. Run your fingers along the lower edge of the rib cage till you locate thexiphoid.
2. Place your thumbs or fingers on the sternum, above the xiphoid & on a line
connecting the nipples.

Techniques
Coordination of chest compression with ventilation
:
1. Thumb technique
- The preferred method
- The two thumbs compress the sternum
- The fingers support the back.
2. Two-fingers technique
- Using the ring & middle fingers OR the index & middle fingers.
- Tips of fingers compress the sternum
- The other hand supports the back.
Note :
- Once the endotracheal tube or laryngeal mask is secure, move to the head of the bed to give
chest compressions. This provides space for safe insertion of an umbilical venous catheter
- An electronic cardiac (ECG) monitor is the preferred method for assessing heart rate
during chest compressions.
1. During chest compression: ensure that chest movement is adequate during ventilation.
2. Compression depth is one third the diameter of the chest.
3. Dura on of downward stroke is shorter than duration of release.
:
1. To ensure proper rate of chest compressionsand ventilation, the compressor
repeats “One-and-Two-and-Three-and-Breathe-and….”
2. One cycle of 3 compressions and 1 breath takes 2 seconds.
- the breathing rate is 30 breaths per minute
- the compression rate is 90 compressions per minute.
* This equals 120 “events” per minute.

If no response to resuscitation:
- After 10 minutes of absent heart rate (HR=0) following complete & adequate
resuscitation efforts → Discontinue resuscitation.
After completing resuscitation
I. The infant who do not require resuscitation :
- should be put on mother’s chest (Kangaroo care), suction if necessary, dry (routine care).
II. A baby who required resuscitation :
- must have post-resuscitation care :
* Parents should be aware with all the steps of resuscitation & should be involved in the decision of
initiation & discontinuation
* close monitoring & frequent assessmentof:
- Respiratory effort, oxygenation,
- Blood pressure, blood glucose, electrolytes,
- Urine output,
- Neurologic status, and
- Temperature during the immediate neonatal period.

Stabilization of preterm Infants:
1. Preterm newborns are at increased risk for requiring resuscitation & assistance with
transition after birth.
2.Preterm newborns are at increased risk of complications because of:
3. Additional resources for a preterm birth include:
a. Immature lungs
b.Immature brains that are prone to bleeding
c. Rapid heat loss
d. Vulnerability to hypoglycemia
e. Vulnerability to severe infection
f. Vulnerability to injury from excessive oxygen

APGAR Score
- It is done to evaluate the success of resuscitative efforts & degree of asphyxia.
- It is done both at one & five minutes of life.
a) A 1 minute score is an index of degree of asphyxia.
” gives an idea of what was going on during labor and delivery”
b) A 5 minute score is an index of likelihood of death or neurological sequelae.
“ gives an idea of response to therapy (resuscitation) “
- Apgar score is a retrospective, highly subjective tool.
- It is never used to prospectively identify babies needing resuscitation.
