Clinical presentation_

1 bleeding ulcer.
2 pain in the tongue is due to involvent of lingual nerve.In such case,pain frm the tongue can b referred to the ear n lower temporal region.
3 Anlyloglossia is restricted mobility of tongue.It is due to infiltration of the floor of the mouth or mandible.
4 dysarticulation_ difficulty in talking is due inability to move the tongue freely.
5 dysphasia is a common presentation frm ca of post 1/3 rd .
6 foetor oris is due to infected necrotic growth.

Choleteatoma

Cholestesteatoma="Skin hn d wrong place"


it has 2 parts

a=matrgx
-made of keratinised squamous epithlm resting on d thin stroma of fibrous tissue

b=central white mass
-consisting of keratin debris produced by matrix
also caled epidermosis/keratoma

* Origin of cholestma

1=presence of congenital cell rests

2=invagination of tympanic membrne 4m d attic in form of retraction pocket=Wittmaacks theory

3=basal cell hyperplasia. The basal cels of germinal layer of skin proliferate due 2 infection=Ruedis theory

4=epithelial invasion. The epithelium 4m d meatus grows in2 middle ear through a pre-existing perforation=Habermans theory

5=metaplasia. Middle ear mucosa undergoes metaplasia due 2 repeated perforation and convert in2 squamous type=Sades theory


* Classification

1. Congenital

- arises 4m d embryonic epidermal cell
- sites: middle ear,petrous apex,cerebellopontine angle
- presents as white mass behind d intact tympanic membrane and causes conductive hearing loss

2. Acquired primary

- there is primary bcos there no history of previous otitis media/perforation
- theories :

a. invagimation of pars flaccida
- persistent -ve pressure in d attic causes a retraction pocket which accumulate keratin debris
b. basal cell hyperplasia
c. squamous metaplasia

3. Acquired secondary

- there is already pre-exisisting perforation in d pars tensa
- always asociated with d posterosuperior marginal or sometimes central perforation

- theories :

a. migration of squamous epithelium
b. metaplsia

* Expansion of cholestoma

- 4m d middle ear invade d surrounding structure and follows d path of least resistance and then enzymatic bone distruction
- attic cholstoma may extends backwards 2 aditus,antrum,mastoid, downward in2 mesotympanum and medialy surrounds d incus

* Distruction of bone

- cholstoma has d property 2 distroy bone e.g. ear occicles, bony labyrinth, canal of facial nerve, sinus plate, tegman tympani

Ca head of pancreas

Ca head of pancreas
Ca head of pancreas


Ca head of pancreas

70% of the cases occurs in the head of the pancreas including periampullary region

AETIOLOGY:-

1. Tropical pancreatitis and hereditary pancreatitis r associated with pancreatic cancer such malignancies can be multifocal
2. Haemochromatosis:-produces extensive calcification of pancreas.Also a precancerous condition
3. Diabetes:-diabetic patients r 10 times more vulnerable for carcinoma of pancreas
4. Other possible aetiological factors:-alcohol and smoking:-it is related to tobacoo specific nitrosamines
 -westernization of diet:-fatty food,rich in animal proteins can cause pancreatic cancer
 -indusrial carcinogens:-B11-naphthylamine,benzidine,gasoline r the possible agents


PATHOLOGY

 -Periampullary refers to carcinoma arising from ampulla of vater,the duodenal mucosa or the lower end of the common bile duct
 -microscopically,types are:
1. Mucus secreting carcinoma of ductal origin
2. Non mucus secreting carcinoma of acinar origin
3. Anaplastic carcinoma are poorly differentiated and tend to arise from the body of the pancreas
4. Cystadenocarcinomas are rare,slow growing and tend to attain a large size

CLINICAL FEATURES


1. Age: 50-70 years
2. Sex: comon in both sexes equally
3. Duration of symptoms: short duration( 1-3 months)
4. Symptoms:
 -pain: there may be some discomfort in abdomen but colicky pain is not a feature.Pain is relatively rare in carcinoma head of pancreas
 -fever: when obstruction becomes severe,there is bile stasis.Cholangitis,fever with cills and rigors can occur
 -jaundice: as a result of slow developing obstruction at periampullary region,jaundice is persistent,progressive,painless,pruritic,in 5% of cases growh may ulberate into the duodenum.It can cause melaena and jaundice may temporarily subside.
 -stools: clay coloured stools are common and when mixed with blood it is called silvery stools or aluminium paint stools
 -pruritus: severe due to bile salts in the circulation
 -loss of appetite: significant
 -loss of weight
5. Signs
 -jaundice: sometimes greenish yellow
 -anaemia: it is usually present
6. Per abdomen
 -liver can be enlarged due to back pressure.If it is nodular,with sharp border,hard in consistency,it is due to secondaries in liver
7. Gall bladder
 -gall bladder is palpable in 70-75% cases
8. Metastasis
 -left supraclauicular node,ascites etc.

D/d:

1. Carcinoma stomach
 such mass may not be mobile.It does not move with respiration because it is fixed to pancreas
 -these patients will have vomiting first followed by backache at a later date
2. Ca transverse colon
 -produces constipation and bleeding per rectum.Vertical mobility may be present.
 -right to left peristalsis may be present
3. Para aortic lymph mass may be due to
 -intra abdominal malignancies,lymphoma,testicular tumor etc

invest

1. Hb% is low in malignancy
2. BT,CT,PT r altered
3. Urine for urobilinogen is negative
4. Serum alkaline phosphatase: increased >500 units
5. Abdominal usg: it is most useful,noninvasive,reliable and quick investigation for obstructive jaundice
 -dilated biliary radicles,both intrahepatic n extrahepatic can be demonstrated
 -stones can be diagnosed with their postier acoustic shadow
 -mass lesion in the head region can be made out in cases of chronic pancreatis or ca head of the pancreas causing obstructive jaundice
7. CT scan:-
8. Endoscopy:-useful to diagose a periampullary carcinoma which may be seen as an ulcerative lesion in the 2nd part of the duodenum,biopsy can also be taken which shows adenocarcinoma
9. Barium meal:
 distortion of the medial border of the duodenum giving rise to inverted 3 sign
 -in ca head of the pancreas there may be widening of C loop of deodenum -Pad sign
10. ERCP ( Endoscopic Retrograde Cholangio Pancreatography)


TREATMENT

surgical treatment

 1. Radical pancreaticoduodenectomy -"whipple's operation"
 -in this operation growth along with 'C' loop of duodenum upto DJ flexure,removal of the head of pancreas upto the neck n partial gastrectomy is done followed by
-pancreaticojejunal anastomosis,gastrojejunostomy n choledochojejunostomy
 2. Pylous preserving pancreaticoduodenectomy PPPD
 in this operation,pylorus is preserved. Thus ,gastric motility is not disturbed
 3. Triple bypass: cholecystojejunostomy +enteroenterostomy +gastrojejunostomy
 this is a palliative surgery in which distended gall bladder is anastomosed to a long loop of jejunum to relieve jaundice.To prevent food particles entering into the gall bladder,enteroenterostomy is done.


Non surgical treatment

 -very elderly patients who r not fit candidates for surgery n patents who have metastasis can be treated by palliative stenting.Howerver,results of a surgical bypass is superor to stenting

position

reclining with head end of tabel raised . Patient lies supine with  face turned

Technique

1. Incisison
a horizontal incision with its end upward is made below gingivolabial sulcus from lateral incisor to 2nd molar it cuts through mucous membrane and periosteum

2 .Elevation of flap
mucoperiosteal flap is raised from the canines fossa to infraorbital nerve

3. Opening the antrum
using cutting burr hole is in antrum

4 Dealing with pathology
after opening maxillary antrum pathology is removed with elavator and foreceps

5 Making nasoantral window
a curved haemostat is pushed into antrum from inferior meatus
and then opening enlarged with kerrisons and sidebiting foreceps

6. Packing the antrum
ribbon guaze impregnated with liqid parrafin can be packed in antrum and its end brought out from nasoantral window into nose  Intrasinus packing is done if there is severe bleeding

7. Closure of wound
sublabial incision is closed with  catgut sutures


post operative care

1 . Ice packs over cheek in first 24 hours prevent odema haematoma
2  packing in sinus and nose can be removed in 24 to 48 hrs
3antibiotics are given for 5 tn 7 days
4  patient should avoid blowing his nose to avoid surgical emphyesema

complications

1 Post operative bleeding
2 injury to nasolacrimal duct

6 anasthesia of cheek due stretching  of  infraorbital nerve

Caput succedaneum

Caput succedaneum
Caput succedaneum

Caput succedaneum

It is the formation of swelling due to stagnation of fluids in the layers of scalp beneath the girdle of contact.
  Girdle of contact may be bony or dilating cervix or vulval ring.
Swelling is diffuse baggy & not limited by the suture lines
mechanism-when head descend to press over the dilating cervix the overlying scalp is free of pressure  but the tissue in contact with the full circumference of the girdle of contact is compressed.This interference with the venous return & lymphatic drainage from unsupported area of scalp leads to stagnation of fluid & appearance of swelling in the scalp .
 It usually occurs after the rupture of membranes.

Importance=

1>it signifies static position of head for a long period of time.
2>location of it gives idea about position of head occupied in the pelvis & the degree of flexion achieved.With increasing flexion caput is placed more posteriorly.

Aetiipahogenesis:

- SAD factors
    Smoking
    Alcohol
    Dietary
- diet rich in red meat has high aminal fat which is responsible for formn of carcinogenic polycyclic aromatic compounds
- colecystectomy- increase in free bile acid conc
- genetic factors

Prrcancerous condns:

- polyps in FAP
- villous adenoma
- ulcerative colitis and cohns dis

Pathological types

- annular-- common at the rectosigmoid jucn, presents with constipation and obstruction, takes abt 12 months for grow to encircle the lumen (napkin ring)
- polypoidal-- common in ampula
- ulcerative-- occures nywhere, hs raised edges and growth occures in transverse direcn
- diffuse-- similar to lininis plastica, develops frm ulcerative colitis, worst prognosis
- colloid-- contents r gelatenous, seen in youngs

C/f

1) constipation requiring incresed dose of pergatives
2) bleeding per rectum--frank blood or mixed with stool, it is never massive, is painless, and is the earliest symptom
3) early morning spurious diarrhoa due to accumulation of mucus overnight ina the ampulla, causes an urgency to pass stools bt results in onlly mucus with minimum stools, thr is always a sence  of incomplete defication
4) tenesmus-- painful incomplete defication asso with bleeding
5) bloody slime-- attempt at defecation results in mucucs mixd with blood
6) loss of apetite, loss of wt due to liver secondaries and abdominal disyension r late features

On exam:

- done in every case of bleeding per rectum
- indurated colinflower like growth or infiltrative ulcer cn b felt
- finger stained with blood
- rectal ca presenting as fistula in ano is equivalent to perforated colon ca, is a bad prognostic sign

DDs

- proctitis
- solitary rectal ulcer syndrome

Spread:

1) local:
    Involves muscle coat and spreads into extrarectal tissue, anteriorly involves prostate seminal vessicals and bladder base in males, and vagina nd uterus in females. Posteriorly sacral plexus
2) lymphatic:
   Frm the upper and middle onethird, spreads upwards first to pararecatl nodes of gerota.
  Frm lowe 1/3 spreads laterally and can involve internal illiac nodes
3) blood spread
 - occures in lung and liver
4) peritoneal spread
 - results in ascitis, malignant nodules

Investigations

-proctoscopy
- signoidoscopy
- barium enema
- colonoscopy
- carcino embryonic antigen levels

Etiology

Circumcision soon after birth confess almost complete immunity against carcinoma of the penis.later circum. does not seem to have d same effect.chronic balanoposthitis is known to b a contributory factor,there r different precarcinomatous states-
-leucoplakia of d glans
-long standing genital warts
-pagets disease of penis is persistent rawness of the glans lik a longstanding balinitis followed by cancer of penis.

Pathology

Carcinoma of the penis may be flat and infiltrating or papillary.it can start as leukoplakia.d earliest lymphatic spread is to the inguinal and then to iliac nodes.once the growth breaches the partial barrier formed by fascial sheath of Corpora cavernosa it spreads rapidly and iliac lymph node involvement is common

C/f

-forty percent patients are under 40 years of age.
-initially discomfort and light discharge
-foul bloody discharge and little or on pain.
-sixty percent have inguinal lymph node enlargement when they present
-prepuce is non retractile
-untreated the whole glans may b replaced by a fungating offensive mass.

Treatment

-radiotherapy is effective (60-70% survival at 5years) if the growth is small.circumcision precedes treatment which may b delivered by implanted radioactive tantalum wires,external beam radiation or by means of radio.mould applicator applied to penis

-surgery is needed if there is infiltration of shaft n when radiotherapy fails.partial amputation used for distal growths.when an advanced infijtrating or anaplastic lesion present total ampu is necessary.

-block dissection of enlarged lymph nodes.

C/F

very often pts wud hav vague symptoms- early satiety, flaulence, discomfort, pain upper abdo
1)Silent growth but manifests as secondaries in liver, ascites, Virchow's node etc
2)Obstructn @ pyloric antrum wid featurs of vomiting wid/widout bld
3)Lump in abdo whch is hard & iregular
4)Insidious in onset- anaemia, anorexia, asthenia of short duration
5)Dyspepsia in man ovr age of 40
Featurs of stomch mass
i)stomch moves wid respi
ii)upper border of stomach mass cn b mad out
iii)anatomicl location of mass- rt hypochondrium in a pyloric mass, epigastrium & lt hypochondrium in a mass arising 4m body of stomch
iv)knee elbow position- mass does fall forwards unles fixd
v)mass may hav intrinsic mobility


SPREAD

1)Penetration of gastric serosa- dis is d most imp prognostic indicator. Wen serosa is not penetrated 50% surviv for 5yr aftr resectn
2)Lymphatic spread
lymph nod invo is a poor progno indicator
invo of 4/more nodes is less favourabl
**Lymphatic Zones

CLINICAL FEATURES

early features of maxillary sinus malignancy are
1. nasal stiffiness
2.Blood stained nasal discharge
3.Facial paraesthesias or pain and epiphora


DIRECTIN OF SPREAD AND EXTENT OF GROWTH

1.Medial spread to nasal cavity gives rise to nasal obstruction, discharge and epistaxis.
2.Anterior spread  cause swelling of the cheek and later invasion of the facial skin.
3.Inferior spread causes expansion of alveolus with dental pain ,loosening of teeth ,poor fitting of dentures. Ulceration of gingiva  and swelling in the hard palate .
4.Superior spread : invades the orbit causing proptosis ,diplopia,occular pain and epiphora.
5.Posterior spread ir into pterygomaxhllary fossa ,pterygoid plates and the musckes causing trismus. Growth may also spread to the nasopharynx,sphenoid sinus and base of skull
6.Intracranial spread
to ethmoid ,cribriform plate or foramen or foramen lacerum
7.Lymphatic spread  occur in the late stage of disease .
Submandibular and upper jugular nodes are enlarged .Maxillary and ethmoid sinuses drain primarily into retropharyngeal nodes, but these nodes are inaccessible to palpation.
8.Systemic metastases
 may be seen in the lungs and occasionally in bone

Cardiac arrest

Cardiac arrest

Definition:-
An abrupt loss of cardiac pump function which may b reversible by a prompt intervention, but will lead 2 death in its absence.

Cardiac arrest may result 4m 1 of 4 mechanisms-
1)Ventricular fibrillation
2)Pulseless ventricular tachycardia
3)Ventricular asystole
4)Pulseless electrical activity

**Causes**

§Ventricular fibrillation
  -myocardial ischaemia or infarction
  -Electrocution
  -Hypokalaemia & hyperkalaemia
  -Drugs
§Ventricular asystole
  -Localised failure of conducting tissue
  -Massive myocardial infarction
§Pulseless electrical activity
  -Cardiac rupture
  -Massive pulmo embolism


**Management**

Cardiopulmonary resuscitation (CPR):-
Provides artificial ventilation & perfusion 2 vital organs i.e heart & brain until spontaneous cardiopulm function is restored
It encompasses both basic life support & advanced life support
1)Basic life support
indicates manoeuvres which, widout special equipment either prevent circulatory & respi arrest or externally support circulation & venti of victim in arrest
 i)Airway
 ii)Breathing
 iii)Circulation
 iv)Defibrillation
2)Advanced life support
Consists of basic life support & use of special equipment & drugs for establishing & maintaining effective venti & circu
