    Dental caries 

    Is a progressive and destructive process causingdecalcification of the tooth enamel, destruction of dentinand cavitation of the teeth.

    It can spread into the tooth pulp and may causeinflammation and abscess.

    Etiology

    Many organisms may cause dental caries.

    Streptococci is such organism, the main cariogenicagent.

    7

    Pathophysiology

    Streptococci produces a extra cellular polysaccharideand forms a plague over the teeth.

    Gradual tooth decay begins following demineralizationof the enamel.

    8

    Destruction of dentin occurs with cavity formationoccurring causing inflammation and abscess formation.

    Biting and contact surface are the most common sites.

    Pathophysiology cont’d 

    9

    Risk factors

    Carbohydrate rich foods especially chocolate which stick toteeth

    Poor oral hygiene with inadequate dental care

    Sleeping with feeding bottle in mouth

    Sweetening agents like honey

    Fluoride deficiency/excess

    10

    Clinical manifestations

    Pits and fissures in biting and contact surfaces commonlyin molars as initial features.

    Cavity formation involving pulp, dental abscess

    Sepsis

    11

    Treatment 

     Analgesics to relieve pain

    Extraction

     Antibiotics

    Preventative measures

    Dietary modification by avoiding carbohydrate rich foodand avoiding oral retaining.

    Use of fluoride tooth paste

     Avoidance of chewing gum, chocolates, bottle feeding… 

    13

    Preventative measures cont’d 

    Good oral and dental hygiene with correct brushingtechnique.

    Mechanical movement of plaque and debris.

    Dental sealant to pits and fissures.

    Regular dental check-up

    14

    Oesophageal stricture 

    Narrowing of the oesaphagus.

     Acquired oesaphageal stricture in childhood are mostlikely a result of reflux oesophagitis, corrosive injury oranastomotic scaring.

    15

    Oesophageal stricture 

    aurorahealthcare.org nejm.org16

    Clinical manifestations

    Drooling

    Inability to swallow saliva and fluids

    Difficulty feeding - ability to take liquids but not solids

    Regurgitation of undigested food

    17

    Diagnostic test

    Oesaphagoscopy - to evaluate the length, character,ability to dilate the defect and the condition of the mucusmembrane.

    18

    25/06/20

    Treatment

    Sedation and dilation (using rubber balloon, dilator)

    Resection with end to end anastomosis

    19

    Gastro-oesophageal reflux(Infant)

    Regurgitation of stomach secretions into the esophagusthrough the gastroesophageal (cardiac) valve.

    Occurs mainly in infants and adolescent

    20

    Gastro-oesophageal reflux cont’d 

    drbrandonfox.com

    21

    Pathophysiology

    Occurs from a neuromuscular disturbance in which thegastroesophageal (cardiac) sphincter.

    The lower portion of the esophagus spasm and allow easyregurgitation of gastric contents into the esophagus.

    22

    Gastro-oesophageal reflux cont’d 

    Regurgitation occurs almost immediately after feeding orwhen the infant is laid down after a feeding.

    If the amount of the reflux is large or constant, an infantdoes not retain sufficient calories and will fail to thrive.

     In addition, aspiration pneumonia or esophageal stricturefrom the constant reflux of hydrochloric acid into theesophagus can occur.

    23

    Clinical manifestations

     Vomiting

    Irritability and apnea may be evident

    Diagnostic test Fiberoptic endoscopy or Oesophagography (barium swallow) will

    show the involved sphincter and the refluxof stomach contents into the esophagus.

    24

    25/06/20

    Treatment 

    Traditional treatment:

    Feed infants a formula thickened with rice cereal whileholding them in an upright position

    Then keeping them upright in an infant chair for 1 hourafter feeding so gravity can help prevent reflux.

    25

    Treatment cont’d

    H2 receptor antagonist Zantac (Ranitidine) or

    Proton pump inhibitor Omeprazole (Prilosec) to reducethe possibility of the stomach acid contents irritating theesophagus.

    26

    Treatment cont’d

    Gastroesophageal reflux is usually a self-limitingcondition.

     As the oesophageal sphincter matures and the childbegins to eat solid food and is maintained in a moreupright position, the problem resolves.

    27

    Treatment cont’d 

    Laparoscopic or surgical myotomy procedure (narrowingof the esophageal sphincter)

    Followed by temporary placement of a NGT.

    28

    Gastroesophageal reflux disease(Adolescent)

     Affects about 20% of adults; symptoms frequently beginin adolescence.

    Irritation to the esophagus occurs when stomachcontents, including hydrochloric acid, reflux through thelower esophageal sphincter and irritate the esophageallining.

    29

    Etiology

    Reflux occurs because of an incompetent sphincterespecially when the adolescent lies supine or when intra-abdominal pressure is increased by a full stomach, liftingor bending, or tight clothing.

    It is potentially dangerous because it can lead to erosion ofthe esophagus with perforation or stricture of theesophagus.

    25/06/20

    Clinical manifestation

    The typical symptom is heartburn that occurs 30-60minutes after a meal.

    31

    Diagnostic Test

    Based on history (typical symptoms of heartburn) and, ifsymptoms are severe.

    Endoscopy to reveal the irritated esophagus(oesophagitis).

    32

    Treatment

    Goal: To provide symptomatic relief and to heal any oesophagitis identified.

     Antacids (relieve pain by decreasing the concentration ofthe stomach acid)

    H2-receptor antagonists (Pepcid or Zantac) to preventheartburn symptoms.

    Proton pump inhibitors such as omeprazole (Prilosec) tohalt the release of stomach acids

    33

    Treatment cont’d 

     Avoid lying down until 3 hours after a meal

    Sleep at night with upper body elevated on a foam wedge.

     Avoid acidic foods: tomato products, citrus fruits, or spicyfoods.

    34

    Treatment cont’d 

     Avoiding foods that delay gastric emptying such as fattyfoods, chocolate, or alcohol and eating smaller portionsmay also be helpful.

    Weight loss, avoiding bending after meals, and removingtight belts are also recommended steps.

    35

    Gastroenteritis

    Inflammation of the lining of the stomach and intestines,may be caused by:

    Bacteria – e.g. Escherichia coli, Salmonella

     Virus – Rotavirus

    Toxins

     Allergies

    The illness may resolve without complications or causemild to severe dehydration.

    36

    7/22

    25/06/20

    Pathophysiology

    Believed that the causative agent damages and destroysepithelial cells lining the intestine causing the followingclinical manifestations.

    Diarrhea occurs when intestinal fluid output overwhelmsthe absorptive capacity of the gastrointestinal tract.

    37

    Pathophysiology 

    The decrease in total body water causes a reduction inintracellular and extracellular fluid but the clinicalmanifestations of dehydration are most closely related tointravascular volume depletion.

    38

    Pathophysiology 

    The 2 primary mechanisms responsible for acute gastroenteritis are:

    damage to the villous brush border of the intestine, causingmalabsorption of intestinal contents and leading to an osmoticdiarrhea, and

    the release of toxins that bind to specific enterocyte receptors andcause the release of chloride ions into the intestinal lumen, leading

    to secretory diarrhea.

    39

    Clinical manifestations

    Nausea

     Vomiting

    Diarrhea

    Fever

    Dehydration

    Electrolyte imbalance

    40

    Diagnostic test

    Stool culture may be done

    41

    Treatment

    IVF

    Electrolytes

     Antibiotics

    Rehydration salts/fluids

    Diet when vomiting and diarrhea subsides

    42

    Nursing management

     Administer and monitor IVF

    Skin care

     Administer medication as ordered

    Offer rehydration fluids

    43

    Diarrhoeal diseases 

    Is the passage of loose, liquid or watery stool at leastthree times per day.

    The recent change in consistency and the character of thestool rather than the number of stool is more important.

    44

    Diarrhoeal diseases

    colon-cleanse-information.com

    45

     Acute Diarrhoea

    Is an attack of loose motion with sudden onset whichusually last 3 – 7 days but may last up to 10 – 14 days.

    Caused by infection of the large intestine but can also beassociated with infection of the gastric mucosa and thesmall intestine.

     Acute GE is usually use to describe acute diarrhoea46

    Chronic Diarrhoea

    When loose motion is occurring for 3 weeks or more.

    Usually related to underlying organic disease with orwithout malabsorption.

    47

    Dysentery

    Diarrhoea with watery stool and visible blood in the stool.

    48

    9/22

    25/06/20

    Persistent Diarrhoea

    Refers to the episode of acute diarrhoea that last for 2weeks or more and may be due to infective state.

    49

    Etiology

     A large number of organism are responsible for acutediarrhoea. The infectious agents are:

     Viruses (Rotavirus, Adenovirus, Enterovirus, measles virus etc.)

    Bacteria (Campylobacter jejuni, E. coli, Shigella, Salmonella,Cholera vibrio, Vibrio parahemolyticus etc.)

    Parasites (E. hystolytica, G. lambia, Cryptosporidium, malariaetc.)

    Fungi (Candida albicans)

    50

    Etiology cont’d 

    Other causes of diarrhoea are related to nutritional anddietary factors:

    Overfeeding

    Underfeeding/malnutrition

    Food allergies

    Food poisoning

    Some drugs such as antibiotics cause diarrhoea51

    Etiology cont’d

    Malnutrition: 

    Children who die from diarrhoea often suffer fromunderlying malnutrition, which makes them morevulnerable to diarrhoea.

    Each diarrhoeal episode, in turn, makes their malnutritioneven worse. Diarrhoea is a leading cause of malnutrition inchildren under five years old.

    52

    Etiology cont’d 

    Source: Water contaminated with human faeces, e.g. fromsewage, septic tanks and latrines, is of particular concern.

     Animal faeces also contain microorganisms that can causediarrhoea.

    Other causes: Diarrhoeal disease can also spread fromperson-to-person, aggravated by poor personal hygiene. Foodis another major cause of diarrhoea when it is prepared orstored in unhygienic conditions. Water can contaminate foodduring irrigation. Fish and seafood from polluted water mayalso contribute to the disease. 53

    Incidence

    Every year there are about two billion cases of diarrhoeal diseaseworldwide.

    Diarrhoeal disease is a leading cause of child mortality and morbidityin the world, and mostly results from contaminated food and watersources.

    Diarrhoea due to infection is widespread throughout developingcountries.

    **Key facts**

    Diarrhoeal disease is the second leading cause ofdeath in children under five years old. It is bothpreventable and treatable.

    Kills 1.5 million children every year.

    Globally, there are about two billion cases of diarrhoealdisease every year.

    Mainly affects children under two years old.

    Leading cause of malnutrition in children under five yearsold.

    55

    Degree of Dehydration

    Rated on a scale of three. Early dehydration/Mild – may or may not have signs or

    symptoms.

    Moderate dehydration:

    thirst

    restless or irritable behaviour

    decreased skin elasticity

    sunken eyes56

    Degree of Dehydration cont’d 

    Severe dehydration:

    shock,

    with diminished consciousness,

    lack of urine output,

    cool moist extremities,

    a rapid and feeble pulse,

    low or undetectable blood pressure,

    and pale skin.

    57

    Diarrhoea

    The most severe threat posed by diarrhoea isdehydration.

    During a diarrhoeal episode, water and electrolytes(sodium, chloride, potassium and bicarbonate) are lostthrough liquid stools, vomit, sweat, urine and breathing.

    Dehydration occurs when these losses are not replaced.

    58

    Diagnostic test

    Stool culture

    Blood culture

    Serology (evaluating antibodies to identify microbes with whichyou have recently been infected)

    59

    Treatment 

    Rehydration with IVF in case of severe dehydration orshock, oral rehydration salts (ORS) solution formoderate or no dehydration.

    Nutrient-rich foods

     Antibiotics (if cause is bacterial agent)

    60

    improved sanitation

    exclusive breastfeeding for the f irst six months of life

    good personal and food hygiene

    health education about how infections spread

    rotavirus vaccination

    61

    Nursing management

     Assess stools for frequency, amount, color, consistency

     Assess S&S of dehydration; ↑po fluid intake

     Assess perianal skin breakdown and provide skin care

    Obtain stool specimen

     Administer antibiotics, antidiarrheals, IVF & electrolytes asordered

    62

    Helminthiasis 

    Infestation of worms

    Common types are:

    Round worms ( Ascaris lubricoides )

    Pinworm or threadworm (Enterobius vermicularis)

    Hook worm ( Ancylostoma duodenale, Necatoramericanus )

    Tape worm (Taenia saginata, Taenia solum )63

    Helminthiasis 

    hon.ch

    infection-research.de

    64

    Etiology

    Helminthiasis in human are caused by three types:

    Nematodes (roundworm, pinworm, hookworm)

    Cestodes (tapeworm)

    Trematodes (fishworm, flukes)

    65

    Roundworm(Ascariasis)

    Most common helminthic infestation.

    Lives in the lumen of the small intestine.

     The adult female round worm measures 20-40 cm andthe male measure 12-30 cm in length.

    66

  • 8/20/2019 Gastrointestinal System Part 2

    12/22

    25/06/20

    Pathophysiology

    The female produces approximately 200,000 to 300,000eggs per day.

    Eggs are excreted in faeces and external environment theybecome infective in favourable conditions.

    Mature eggs when ingested hatches in the duodenum torelease larvae.

    67

    Pathophysiology cont’d

    The larvae penetrates the intestine, and are carried toliver then lung in the blood stream.

    They break through the alveolar wall while in the lungand migrates into the bronchioles, get coughed upthrough the trachea.

    68

    Pathophysiology cont’d

    They get re-swallowed to reach the small intestine, wherethey become adult worms in 60 to 80 day. They have a lifespan of 1.5 to 2 years.

    69

    Worm cycle

    70

    Montresor & Diarra, n.d (WHO)

    Transmission

    Mode of transmission: Feco-oral route of ingestion ofinfective eggs with food or soil or drink or bycontaminated hands and fingers.

    Communicable period: Continued until all fertile eggsare destroyed and stools are negative of roundwormeggs.

    Incubation period: About 2 months71

    Hepatitis A

    Causative agent: A picornavirus, hepatitis A virus (HAV)

    Incubation period: 25 days on average

    Period of communicability: Highest during 2 weekspreceding onset of symptoms

    111

    Hepatitis A cont’d 

    Mode of transmission:

    In children, ingestion of fecally contaminated water orshellfish

    Day care center spread from contaminated changing tables

    Type A occurs in children of all ages and accounts for

    approximately 30% of instances.112

    Hepatitis A cont’d 

    Immunity:

    Natural; one episode induces immunity for the specifictype of virus

     Active artificial immunity: HAV vaccine (recommended forall children 12 to 23 months of age and workers in daycare centers)

    Passive artificial immunity: Immune globulin

    113

    Hepatitis B 

    Causative agent: A hepadnavirus; hepatitis B virus (HBV)

    Incubation period: 120 days on average

    Period of communicability: Later part of incubation periodand during the acute stage

    Hepatitis B cont’d  Mode of transmission:

    Transfusion of contaminated blood and plasma or semen Inoculation by a contaminated syringe or needle through IV

    drug use May be spread to fetus if mother has infection in third

    trimester of pregnancy

    Tends to occur in newborns from placental-fetal transfer andin adolescents after intimate contact or the use ofcontaminated syringes for drug injection.

    115

    Hepatitis B cont’d 

    Immunity:

    Natural; one episode induces immunity for the specifictype of virus

     Active artificial immunity: Vaccine for the HBV virusrecommended for routine immunization beginning at birthand also to all health care providers

    Passive artificial immunity: Specific hepatitis B immuneserum globulin

    116

    Hepatitis C

     Hepatitis C is a single-strand RNA virus.

    Transmission is primarily by blood or blood products, IVdrug use, or sexual contact.

    The virus produces mild symptoms of disease, but there

    is a high incidence of chronic infection with the virus.117

    Hepatitis D

    Is similar to HBV in transmission, although it apparentlyrequires a coexisting HBV infection to be activated.

    Disease symptoms are mild, but there is a high incidenceof fulminant hepatitis after the initial infection.

    118

    Hepatitis E

     Enterically transmitted similarly to hepatitis A (fecallycontaminated water).

    Disease symptoms from the E virus are usually mild,except in pregnant women, in whom they tend to besevere.

    119

    Hepatitis 

    Clinically, it is impossible to differentiate the type ofhepatitis from the signs that are present.

    Pathophysiology

    The virus attacks the parenchymal cells, resulting in localdegeneration and necrosis of the tissue.

    This stimulates the inflammatory process.

    121

    Pathophysiology cont’d 

    Swelling and accumulation of WBC blocks the liver tissue,resulting in an elevation in bilirubin and ALT and alkalinephosphatase in the blood.

    The liver fails to produce enough albumin, resulting ingeneralized edema.

    122

    Diagnostic test

    Laboratory studies - liver enzymes

    Bilirubin (levels are increased in the urine)

    Bile pigments (levels in the stool are decreased)

    Serum bilirubin (levels are increased)

    123

    Treatment 

    Supportive measurement and bed rest

    Hepatitis A is self limiting and does not result in chronicHepatitis

    No treatment exist for Hepatitis B, antiviral is given for

    chronic Hep. B.124
