This document discusses birth canal trauma and uterus rupture. It defines the birth canal as the passage from the uterus through the cervix, vagina, and vulva. Birth canal trauma can occur in the cervix, vagina, or perineum and is classified based on location and severity. Cervical lacerations range from first to third degree tears. Vaginal lacerations can be traumatic or spontaneous. Perineal lacerations also range from first to fourth degree. Factors like nulliparity, fetal size, and position can increase risk of lacerations. Episiotomies are sometimes performed to prevent lacerations. Uterus rupture is a serious complication where the uterus tears,

A serious pregnancy complication in which the placenta detaches from the womb (uterus).
Placental abruption occurs when the placenta detaches from the inner wall of the womb before delivery. The condition can deprive the baby of oxygen and nutrients.
Symptoms include vaginal bleeding, stomach pain and back pain in the last 12 weeks of pregnancy.
Depending on the degree of placental separation and how close the baby is to full-term, treatment may include bed rest or a Caesarean (C-section).

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.

2. Definition of birth canal:
- The passageway through which the fetus
is expelled during parturition, leading
from the uterus through cervix, vagina
and vulva.
- Vagina, vulva and perineum are often
injured during expulsion stage of labor
WHAT IS BIRTH CANAL?
5. The types of trauma in birth canal is
classified based on localisation :
- Cervix
- Vagina
- Perineum
BIRTH CANAL TRAUMA
6. CERVICAL LACERATIONS
- Cervical tears are most presented in the lateral cervical
sides
- Rupture of the cervix is characterized by persistent
bleeding from a contracted firm uterus
There are 3 degrees of cervical lacerations:
1. First degree lacerations
- Length of cervical rupture not over 2cm
2. Second degree lacerations
- Length of rupture >2cm but does not extend to vaginal
fornices
3. Third degree lacerations
- Ruptured area extends to the vaginal fornices
- If extends to vaginal fornices : very dangerous
7. - Rigidity of cervix
- Abnormal structure due to scarring from
previous surgery
- Rapid delivery of head in breech
presentation
CAUSES OF CERVICAL
LACERATIONS
8. TREATMENT OF CERVICAL
LACERATIONS
• Deep cervical tears should be repaired immediately
• Treatment varies with the extent of the lesion.
When the laceration is limited to the cervix – or even when it
extends somewhat into vaginal fornix
• We can view the cervical
tears at the vulva by applies
firm downward pressure on
the uterus while the operator
exerts traction on the lips
of the cervix with
fenestrated ovum or sponge
forceps
9. VAGINAL LACERATIONS
- Usually longitudinal
- Lacerations frequently extend deep into the
underlying tissues and may give rise to
significant hemorrhage
- Causes of vaginal lacerations can be
traumatic or spontaneous:
- The repair of vaginal tears is in placing of interrupted
catgut suture in the edges of the wound
TRAUMATIC SPONTANEOUS
Injuries during forceps
delivery
Fetal malpresentation (Esp
fetal head extension)
Insufficient distensibility of
vaginal wall
Large fetal head
10. - Classification of perineal lacerations:
- 1. First degree
- 2. Second degree
- 3. Third degree
- 4. Fourth degree
PERINEUM LACERATIONS
Delivery may lead to overstretching of the vagina, causing tears
in the perineum, between the vagina and rectum.
11. - The least severe
- Superficial tear that involve perineal
skin ,underlying tissue and superficial
muscle ( musculus constrictor ani)
FIRST DEGREE LACERATION
13. THIRD DEGREE LACERATION
- Lacerations extend farther to involve perineal
body and circular muscle sphincter ani
14. - The most severe type
- The laceration extends through the rectum’s
mucosa to expose anorectal lumen
FOURTH DEGREE LACERATION
15. Factors predisposing
to Laceration of Perineum
Factors which increase risk of third- and
fourth-degree lacerations:
1. Nulliparity
2. Prolong second-stage of labor
3. Persistent occiput posterior position
4. Mid or low forceps
5. Asian race (height)
6. Giant baby / macrosomia
7. Rigidity of perineal muscle
8. Epidural/peridural anesthesia
16. EPISIOTOMY
- Also known as perineotomy
- Incision of perineum and posterior vaginal
wall during second stage of labor
- Purposes of episiotomy :
- Easier to repair the laceration
- postoperative pain is less and healing
improved with an episiotomy compared
with a tear
- prevent pelvic floor complications
(vaginal wall support defects and
incontinence)
17. -
Indications of Episiotomy
- When see threatening signs of perineal
laceration
- The baby is very large ( need to deliver
quickly to avoid any resistance)
- When the perineal muscles are excessively
rigid
18. -
Types of Episiotomy
Median or Midline episiotomy Mediolateral episiotomy
Incision is made at midline,
from center of the
fourchette and extends on
posterior side along
midline for 2.5 cm
begin in the midline but be
directed laterally and
downward away from the
rectum, either to left or right
about 2.5cm from the anus
(midpoint between anus and
ischial tuberosity)
Better because it wouldn’t
extend until anus
19. -
Midline episiotomy being made. Two fingers are
insinuated between the perineum and fetal head,
and the episiotomy is then cut vertically downward
20. -
Episiotomy Repair
The repair of perineal tears is same as episiotomy incisions
1. Repair of first-degree lacerations
- start from the upper angle of the wound
- The vaginal mucosa is closed by interrupted catgut
suture. And then the perineal skin are sutured
- The sutured wound should be treated with an iodine tincture
2. Repair of second-degree lacerations
- The upper angle of the wound is first sutured
- Then the lacerated perineal muscles are repaired by several
buried catgut sutures
- After that, the same technique as in the first-degree
lacerations
21. Episiotomy Repair
3. Repair of Third-degree lacerations
- rectal mucosa has been repaired with interrupted, fine
chronic catgut sutures
- The torn ends of the sphincter ani are next approximated
with two or three interrupted chromic catgut sutures
- The wound is then repaired, as in a second degree
laceration
22. Uterus Rupture
- One of the most dangerous labor complication
- A spontaneous or traumatic rupture of the uterus
with extrusion of the fetus or fetal parts into the
peritoneal cavity
- By definition, it is associated with the following:
- Clinically significant uterine bleeding
- Fetal distress
- Protrusion or expulsion of the fetus and/or
placenta into the abdominal cavity
- Need for prompt cesarean delivery
- Uterine repair or hysterectomy
23. Classification of Uterus Rupture
1. Classification by Pathogenesis
Spontaneous
- Histochemical etiology of
uterine rupture
- occurs without any function of
uterus
- Example:
(i) Anatomy anomaly
(ii) Dystrophy diseases
(connective tissue autoimmune
disease, Inflammatory disease of
uterus)
Voluntary
- result of hyperfunction of uterus
- Example:
(i) Disproportion between sizes
of presenting part and
maternal pelvis
(malpresentation)
(ii) Extra doses of uterotonic
drugs
24. Classification of Uterus Rupture
2. Classification by Layers of Uterus involved in
Rupture
Complete rupture Incomplete rupture
3. Classification by Location of Rupture
Lower segment rupture Rupture of corpus/fundus
of uterus
25. Signs of Threatened Uterine
Uterus Rupture
- Signs that occur just during the labor
- Excessive uterine activity. Uterine
contractions are very fast and painful
- Lower uterine segment is overdistended,
thinned and painful at palpation
- The margins of the cervical os becomes
edematous due to compression. The
edematous extends to the vagina and the
perineum
- Urination becomes difficult due to
compression of the bladder and urethra
between the bony pelvis and the fetal head
- Some bloody discharge maybe presented
(depends)
- Pathological contractile Bandl’s ring is
presented
27. -Uterine contractions suddenly stop
-Palpation of fetus in the abdomen (outside
the uterus)
-Fetal death
-Hemorrhage then hypovolemic shock in
mother
Signs and Symptoms in the Uterine
Rupture that has happened
28.
29. Treatments of Uterine Rupture
Whenever a threatening uterus rupture is
seen, immediate Caesarian section must be
done!
30. Managements of Uterine Rupture
- blood transfusion
- Emergency exploratory laparotomy with
cesarean delivery
- Surgical repair of uterus or removal of uterus
(hysterectomy), types of surgical treatment
depends on Type of uterine rupture :
- Extent of uterine rupture
- Degree of hemorrhage
- General condition of the mother
- Mother’s desire for future childbearing
When the tear is simple, transverse in the
lower segment, and in the absence of infection
=> Repair by suturing
When the ruptures were longitudinal on the
lateral aspects of lower and upper segments of
the uterus and the bleeding is uncontrollable
(severe) => Hysterectomy
