Ludwig's Angina
• Is a skin infection that occurs on the floor of the mouth, underneath the tongue.
• Complications can be life threatening.
Causes:-• Ludwig’s angina is a bacterial infection. It is usually caused by
the bacterium Streptococcus or Staphylococcus and often follows a mouth injury or infection such as a tooth abscess.
• Poor dental hygiene, lacerations in the mouth or a recent tooth extraction.
![Page 3: Final ppt shadab](https://reader036.fdocuments.in/reader036/viewer/2022081515/554e99feb4c905fc368b516e/html5/thumbnails/3.jpg)
Symptoms:- Ludwig’s angina often follows a tooth infection or other infection or injury in the mouth.
Symptoms include:• pain in the floor of your mouth• problems with speech• neck pain• swelling of the neck• redness on the neck• weakness, fatigue• earache• swollen tongue pushing against your palate• fever, chills
![Page 4: Final ppt shadab](https://reader036.fdocuments.in/reader036/viewer/2022081515/554e99feb4c905fc368b516e/html5/thumbnails/4.jpg)
Diagnosis:-• Physical exam:-Head, neck and tongue will appear red and
swollen.• Imaging tests:-Contrast-enhanced magnetic resonance
imaging (MRI) or computed tomography (CT) images.• Fluid cultures :-Fluid from the affected area may tested to
identify the bacterium.
Complications:-• Blocked airway.• Sepsis (a severe reaction to bacteria or other germs)• Septic shock(infection that leads to dangerously low blood
pressure).
![Page 5: Final ppt shadab](https://reader036.fdocuments.in/reader036/viewer/2022081515/554e99feb4c905fc368b516e/html5/thumbnails/5.jpg)
Treatment:-• Blocked airway
- Insert a breathing tube through your nose or mouth into your lungs.
- Tracheotomy.• Surgery.• Antibiotics.
Prevention:-• Practicing good oral hygiene.• Having regular dental checkups.• Seeking prompt treatment for tooth and mouth infections.
![Page 6: Final ppt shadab](https://reader036.fdocuments.in/reader036/viewer/2022081515/554e99feb4c905fc368b516e/html5/thumbnails/6.jpg)
Oral Mucositis• Oral Mucositis (OM) refers to an inflammatory, erosive and
ulcerative process inside the mouth, which is usually caused by radiation or chemotherapy.
Causes:-• Side effect of cancer treatment. Increased risk:-• Smoking.• Drinking alcohol.• Eating spicy foods.• Dehydration.• Dry mouth–is another side effect of radiotherapy and
chemotherapy.• Receiving a higher dose of chemotherapy.
![Page 7: Final ppt shadab](https://reader036.fdocuments.in/reader036/viewer/2022081515/554e99feb4c905fc368b516e/html5/thumbnails/7.jpg)
Symptoms:-The symptoms of oral Mucositis usually begin five to 10 days after starting chemotherapy or 14 days after starting radiotherapy.
• Burnt sensation while eating very hot food. • Develop white patches or ulcers on the lining of mouth, on
tongue and around lips.• Red and inflamed oral mucosa. • Ulcerations may cause severe pain.
Conditions look like Oral Mucositis:-• Candidiasis (oral thrush);• Herpes simplex virus (HSV); and• Graft-versus-host disease (GVHD).
![Page 8: Final ppt shadab](https://reader036.fdocuments.in/reader036/viewer/2022081515/554e99feb4c905fc368b516e/html5/thumbnails/8.jpg)
Diagnosis:-• Examining your mouth.• Diagnosis symptoms of pain.• Checking ability to eat and drink properly.
Complications:-• Severe pain and trouble eating .• Dry mouth.• Alterations in taste that can lead to Anorexia.• Weight loss.• Weakness due to poor nutrition.• Severe inflammation and injury to the oral mucosa also
increases the chance of other infections in the mouth and body.
• Cause a reduction in dose of treatment.
![Page 9: Final ppt shadab](https://reader036.fdocuments.in/reader036/viewer/2022081515/554e99feb4c905fc368b516e/html5/thumbnails/9.jpg)
Treatment• Self-care- Avoid tobacco, alcohol and hot & spicy foods.- Drink plenty of fluids.• Palifermin is given by injection which encourages the growth
of new cells on the lining of the mucous membrane.
![Page 10: Final ppt shadab](https://reader036.fdocuments.in/reader036/viewer/2022081515/554e99feb4c905fc368b516e/html5/thumbnails/10.jpg)
Adenoiditis• Adenoiditis is an inflammation of
the adenoids. • Adenoids are masses of lymph
tissue that help the body fight infection.
• Adenoids are found in the pharynx (throat) just behind the nose and are the first line of defense in your throat.
Causes:-• Adenoiditis can be caused by a
bacterial infection, such as Streptococcus, or by viruses such as the Epstein-Barr virus.
![Page 11: Final ppt shadab](https://reader036.fdocuments.in/reader036/viewer/2022081515/554e99feb4c905fc368b516e/html5/thumbnails/11.jpg)
Risk:- Certain risk factors are:• Recurring infections in the throat, neck, or head.• Infections of the tonsils.• Contact with airborne viruses, germs and bacteria.
Symptoms:-. • Difficult to breathe through nose.• Sounding “nasal” when speaking.• Sore or dry throat from breathing through the mouth.• Snoring during the night or any time you sleep.• Signs of infection, such as a runny nose that produces green
or discolored mucus.

Congenital Anomalies
Oesophageal Atresia and Tracheo-oesophageal Fistula
1 in 4425 live births.Congenital esophageal atresia (EA) represents a failure of the esophagus to develop as a continuous passage. Instead, it ends as a blind pouch. Tracheoesophageal fistula (TEF) represents an abnormal opening between the trachea and esophagus
![Page 16: Final ppt shadab](https://reader036.fdocuments.in/reader036/viewer/2022081515/554e99feb4c905fc368b516e/html5/thumbnails/16.jpg)
Clinical FeaturesHypersalivationRegurgitation of every feedAttacks of coughCyanosis
Death usually results fromAsphyxiaAspiration pneumoniaFluid-electrolyte imbalance
The most immediate and effective treatment in the majority of cases is a surgical repair to close the fistula/s and reconnect the two ends of the esophagus to each other.

Signs and symptomsDysphagia (difficulty in swallowing),Regurgitation of undigested food, Chest pain behind the sternum,Weight loss. Coughing when lying in a horizontal position.Cardiospasm. It can be extremely painful in some sufferers. Food and liquid, including saliva, are retained in the esophagus and may be inhaled into the lungs (aspiration).
Investigations
Barrium swallowEndoscopy
![Page 21: Final ppt shadab](https://reader036.fdocuments.in/reader036/viewer/2022081515/554e99feb4c905fc368b516e/html5/thumbnails/21.jpg)
ManagementForceful pneumatic dialatation using a 30-35mm diameter endoscopically postioned balloon disrupts the oesophageal sphincter and improves symptoms in 80% of patients
Endoscopically directed injection of botulinum toxin into the lower oesophageal sphincter induces clinical remission,but late relapse is common.

Hiatus Hernia Hiatus hernia or hiatal hernia is the protrusion (or herniation) of the upper part of the stomach into the thorax through a tear or weakness in the diaphragm.
ClassificationSliding (Oesophago-Gastric) Hiatus Hernia- 90%Rolling (Paraoesophageal) Hiatus Hernia- 5%Mixed (Transitional) Hiatus Hernia- 5%
![Page 24: Final ppt shadab](https://reader036.fdocuments.in/reader036/viewer/2022081515/554e99feb4c905fc368b516e/html5/thumbnails/24.jpg)
EtiologyFailure of the muscle fibres of the diaphragm that forms the margin of the oesophageal hiatus
Short oesophagus
Degenaration of muscle due to aging
Increased intra-abdominal pressure
Recurrent Oesophageal regugitation and spasm causing inflammation and fibrosis
Increase in fatty tissue in obease people causing decreased muscular elasticity of diaphragm
![Page 25: Final ppt shadab](https://reader036.fdocuments.in/reader036/viewer/2022081515/554e99feb4c905fc368b516e/html5/thumbnails/25.jpg)
Signs and symptomsHiatal hernia has often been called the "great mimic" because its symptoms can resemble many disorders.
Dull pains in the chest,shortness of breath(caused by the hernia's effect on the diaphragm),
Heart palpitations (due to irritation of the vagus nerve),
Swallowed food "balling up" and causing discomfort in lower esophagus until it passes on to stomach.
Heartburn (retrosternal burning sensation)
Regurgitation of gastric juice into the mouth
![Page 26: Final ppt shadab](https://reader036.fdocuments.in/reader036/viewer/2022081515/554e99feb4c905fc368b516e/html5/thumbnails/26.jpg)
Management1.To minimise gastro-oesophageal reflux
Elevate bed head by 20cmAvoid posture precipitating reflux,bending or stooping forwards,sitting in a low chairAvoid large mealNo food or drink for 3-4 hours before bedtimeReduce weight if possibleNo smokingAvoid all non dteridal anti-inflammatory drugsAvoid food which provoke syptoms eg: pastries, coffee
2.Reduce gastric acidity and pepsin secretion(Renitidine,Cimetidine, Famotidine)
3.Increase tone of lower oesophageal sphincterMetoclopramide 10 mg tds

Oesophageal Webs and Rings
Esophageal webs are thin (2-3mm) membranes of normal esophageal tissue consisting of mucosa and submucosa that can partially protrude/obstruct the esophagus.
A Schatzki ring or Schatzki-Gary ring
is a narrowing of the lower part of the esophagus that can causedifficulty swallowing (dysphagia). The narrowing is caused by a ring of mucosal tissue (which lines the esophagus) or muscular tissue.

PEPTIC ULCER• Peptic ulcer disease refers to painful sores or ulcers in the lining of
the stomach or first part of the small intestine, called the duodenum.
CAUSES OF PEPTIC ULCER• ulcer is the end result of an imbalance between digestive fluids in
the stomach and duodenum. Ulcers can be caused by:• Infection with a type of bacteria called Helicobacter pylori (H.
pylori)• Use of painkillers called no steroidal anti-inflammatory drugs
(NSAIDs), such as aspirin, naproxen (Aleve, Anaprox, Naprosyn, and others), ibuprofen (Motrin, Advil, Midol, and others), and many others available by prescription. Even safety-coated aspirin and aspirin in powered form can frequently cause ulcers.
• Excess acid production from gastrinomas, tumors of the acid producing cells of the stomach that increases acid output
![Page 35: Final ppt shadab](https://reader036.fdocuments.in/reader036/viewer/2022081515/554e99feb4c905fc368b516e/html5/thumbnails/35.jpg)

TREATMENT AND DIAGNOSIS
DIAGNOSIS:The diagnosis of an ulcer is made by either a barium upper
gastrointestinal X-ray (Upper GI series) or an Upper GI endoscopy
Treatment:• The goal of ulcer treatment is to relieve pain, heal the ulcer,
and prevent complications. .• The first step in treatment involves the reduction of risk
factors (NSAIDs and cigarettes).and second is medications:• Antacids• Proton-pump inhibitors (PPIs)
![Page 37: Final ppt shadab](https://reader036.fdocuments.in/reader036/viewer/2022081515/554e99feb4c905fc368b516e/html5/thumbnails/37.jpg)
Gastric ulcer
• A gastric ulcer is a sore in the lining of your stomach. CAUSES:• Upsets in the balance of stomach acid and digestive juices can
lead to an ulcer. This can be caused by:• Helicobacter pylori (H. pylori) infection• NSAIDsRisk Factors:• Taking NSAIDs for a long time and at higher doses• Cigarette smoking• Alcohol abuse
![Page 38: Final ppt shadab](https://reader036.fdocuments.in/reader036/viewer/2022081515/554e99feb4c905fc368b516e/html5/thumbnails/38.jpg)
Symptoms:• Gnawing pain• Bloating• Burping• Weight lossDiagnosis: Physical examination
Treatment:Talk to your doctor about the best treatment plan for you. Treatment options may
include one or more of the following:• Medication
• Lifestyle Changes
• Surgery and Endoscopy

Gastritis• Gastritis occurs when the lining of the stomach becomes
inflamed or swollen.• Gastritis can last for only a short time (acute gastritis), or
linger for months to years (chronic gastritis).Causes:• Alcohol abuse• Eating or drinking caustic or corrosive substances (such as
poisons)• Extreme stress• Certain medications, such as aspirin

SYMPTOMS :-• The most common symptoms of ulcerative colitis are
abdominal pain and bloody diarrhea. Patients also may experience.
• Anemia• Fatigue.• Weight loss• Loss of appetite• Rectal bleeding• Loss of body fluids and nutrients • Skin lesions• Joint pain• Growth failure (specifically in children)
![Page 54: Final ppt shadab](https://reader036.fdocuments.in/reader036/viewer/2022081515/554e99feb4c905fc368b516e/html5/thumbnails/54.jpg)
DIAGNOSIS
• Many tests are used to diagnose ulcerative colitis. A physical exam and medical history are usually the first step.
• Blood tests may be done to check for anemia, which could indicate bleeding in the colon or rectum .
• In addition, a stool sample allows the doctor to detect bleeding or infection in the colon or rectum caused by bacteria, a virus, or parasites.

Disorders of Tongue• Glossodynia (burning mouth
syndrome)- spontaneous burning, discomfort, pain, irritation, or rawness of the tongue, has no identifiable etiology most of the time
• Etiology- – Idiopathic, Infection,
Allergic/contact hypersensitivity, Mechanical trauma
– Xerostomia, Geographic tongue/ Fissured tongue
– Vesiculobullous disease, temporomandibular dysfunction

Glossodynia Treatment
Treatment for burning mouth syndrome varies greatly between cases based on the severity of the symptoms, the underlying cause and the diagnosis of the physician. In many cases the symptoms will be associated with a psychological disorder such as depression and the burning mouth and the underlying cause will be treated together with anti-depressants. In other cases patients can try altering their medication, using different toothpastes, checking their dentures and increasing their consumption of vitamin B12.

What is cirrhosis?
• Cirrhosis is a condition in which the liver slowly deteriorates and malfunctions due to chronic injury. Scar tissue replaces healthy liver tissue, partially blocking the flow of blood through the liver
![Page 74: Final ppt shadab](https://reader036.fdocuments.in/reader036/viewer/2022081515/554e99feb4c905fc368b516e/html5/thumbnails/74.jpg)
What causes cirrhosis?
• heavy alcohol consumption• chronic hepatitis C (the most common)• Obesity• Autoimmune inflammation of the liver• Metabolic disorders
![Page 75: Final ppt shadab](https://reader036.fdocuments.in/reader036/viewer/2022081515/554e99feb4c905fc368b516e/html5/thumbnails/75.jpg)
What are the symptoms of cirrhosis?
Symptoms are hard to catch in the early stages of the disease. However, as the disease progresses, a person may experience the following symptoms:
• weakness• fatigue• loss of appetite• nausea• vomiting• weight loss• abdominal pain and bloating • itching• spiderlike blood vessels on the skin
![Page 76: Final ppt shadab](https://reader036.fdocuments.in/reader036/viewer/2022081515/554e99feb4c905fc368b516e/html5/thumbnails/76.jpg)

DESEASES OF GALL BLADDER
![Page 78: Final ppt shadab](https://reader036.fdocuments.in/reader036/viewer/2022081515/554e99feb4c905fc368b516e/html5/thumbnails/78.jpg)
Gallstones
Gallstones develop when cholesterol and other substances in the bile form crystals that become hard stones in the gallbladder. The gallbladder is a small sac located just under the liver. Gallstones can form when too much cholesterol is in the bile or when the gallbladder does not empty properly.
![Page 79: Final ppt shadab](https://reader036.fdocuments.in/reader036/viewer/2022081515/554e99feb4c905fc368b516e/html5/thumbnails/79.jpg)
Symptoms
• Pain in the RUQ– Most common and typical symptom– May last for a few minutes to several hours– Mostly felt after eating a heavy and high-fat
meal
• Pain under right shoulder when lifting up arms
• Fever, nausea and vomiting • Jaundice (obstruction of the bile duct
passage)• Acute pancreatitis (gallstone enters the duct
leading to pancreas and blocks it)
![Page 80: Final ppt shadab](https://reader036.fdocuments.in/reader036/viewer/2022081515/554e99feb4c905fc368b516e/html5/thumbnails/80.jpg)
Diagnosis• Ultrasound
– Most sensitive and specific test for gallstones
• Computerized tomography (CT) scan – May show gallstones or
complications, such as infection and rupture of GB or bile ducts
• Cholescintigraphy (HIDA scan) – Used to diagnose abnormal
contraction of gallbladder or obstruction of bile ducts
• Endoscopic retrograde cholangiopancreatography (ERCP) – Used to locate and remove
stones in bile ducts• Blood tests
– Performed to look for signs of infection, obstruction, pancreatitis, or jaundice

Treatment• Surgery:
Cholecystectomy (gallbladder removal) – 5 - 40% of patients develop
postcholecystectomy syndrome (gastrointestinal distress and persistent pain in the RUQ)
– 20% of patients develop chronic diarrhea
• Two surgical options– Open cholecystectomy– Laparoscopic
cholecystectomy
![Page 82: Final ppt shadab](https://reader036.fdocuments.in/reader036/viewer/2022081515/554e99feb4c905fc368b516e/html5/thumbnails/82.jpg)
• Nonsurgical treatment:– Only in special situations
• When a patient has a serious medical condition preventing surgery
• Only for cholesterol stones
– Oral dissolution therapy• Ursodeoxycholic acid - to dissolve cholesterol
gallstones• Months or years of treatment may be necessary
before all stones dissolve
– Contact dissolution therapy • Experimental procedure• Involves injecting a drug directly into the
gallbladder to dissolve cholesterol stones

DIABETES MELLITUS• DM is a group of metabolic diseases in which a person has
high blood sugar, either because the pancreas does not produce enough insulin, or because cells do not respond to the insulin that is produced.
• Types :1. Type 1 DM results from the body's failure to produce insulin.2. Type 2 DM results from insulin resistance, a condition in
which cells fail to use insulin properly, sometimes combined with an absolute insulin deficiency.
3. Gestational diabetes
