INTRODUCTION

Tonsillopharyngitis is acute infection of the pharynx, palatine tonsils, or both. Symptoms may include sore throat, dysphagia, cervical lymphadenopathy, and fever. Diagnosis is clinical, supplemented by culture or rapid antigen test. Treatment depends on symptoms and, in the case of group A β-hemolytic streptococcus, involves antibiotics.

Etiology

The tonsils participate in systemic immune surveillance. In addition, local tonsillar defenses include a lining of antigen-processing squamous epithelium that involves B- and T-cell responses.

Tonsillopharyngitis of all varieties constitutes about 15% of all office visits to primary care physicians.

Etiology

Tonsillopharyngitis is usually viral, most often caused by the common cold viruses (adenovirus, rhinovirus, influenza, coronavirus, respiratory syncytial virus), but occasionally by Epstein-Barr virus, herpes simplex virus, cytomegalovirus, or HIV.

In about 30% of patients, the cause is bacterial. Group A β-hemolytic streptococcus (GABHS) is most common (see Gram-Positive Cocci: Streptococcal and Enterococcal Infections), but Staphylococcus aureus, Streptococcus pneumoniae, Mycoplasma pneumoniae, and Chlamydia pneumoniae are sometimes involved. Rare causes include pertussis, Fusobacterium, diphtheria, syphilis, and gonorrhea.

GABHS occurs most commonly between ages 5 and 15 and is uncommon before age 3.

Symptoms and Signs

Pain with swallowing is the hallmark and is often referred to the ears. Very young children who are not able to complain of sore throat often refuse to eat. High fever, malaise, headache, and GI upset are common, as are halitosis and a muffled voice. A scarlatiniform or nonspecific rash may also be present. The tonsils are swollen and red and often have purulent exudates. Tender cervical lymphadenopathy may be present. Fever, adenopathy, palatal petechiae, and exudates are somewhat more common with GABHS than with viral tonsillopharyngitis, but there is much overlap. GABHS usually resolves within 7 days. Untreated GABHS may lead to local suppurative complications (eg, peritonsillar abscess or cellulitis) and sometimes to rheumatic fever or glomerulonephritis.

Diagnosis

Clinical evaluation GABHS ruled out by rapid antigen test, culture, or both

Pharyngitis itself is easily recognized clinically. However, its cause is not. Rhinorrhea and cough usually indicate a viral cause. Infectious mononucleosis is suggested by posterior cervical or generalized adenopathy, hepatosplenomegaly, fatigue, and malaise for > 1 wk; a full neck with petechiae of the soft palate; and thick tonsillar exudates. A dirty gray, thick, tough membrane that bleeds if peeled away indicates diphtheria (rare in the US).

Because GABHS requires antibiotics, it must be diagnosed early. Criteria for testing are controversial. Many authorities recommend testing with a rapid antigen test or culture for all children. Rapid antigen tests are specific but not sensitive and may need to be followed by a culture, which is about 90% specific and 90% sensitive. In adults, many authorities recommend using the following 4 criteria:

History of fever Tonsillar exudates

Absence of cough

Tender anterior cervical lymphadenopathy

Patients who meet 1 or no criteria are unlikely to have GABHS and should not be tested. Patients who meet 2 criteria can be tested. Patients who meet 3 or 4 criteria can be tested or treated empirically for GABHS.

Treatment

Symptomatic treatment Antibiotics for GABHS

Tonsillectomy considered for recurrent GABHS

Supportive treatments include analgesia, hydration, and rest. Penicillin V is usually considered the drug of choice for GABHS tonsillopharyngitis; dose is 250 mg po bid for 10 days for patients < 27 kg and 500 mg for those> 27 kg (see also Gram-Positive Cocci: Pharyngitis). Amoxicillin Some Trade Names AMOXILTRIMOXClick for Drug Monograph is effective and more palatable if a liquid preparation is required. If compliance is a concern, a single dose of benzathine penicillin 1.2 million units IM (600,000 units for children ≤ 27 kg) is effective. Other oral drugs include macrolides for patients allergic to penicillin, a 1st-generation cephalosporin, and clindamycin Some Trade Names CLEOCIN

Treatment may be started immediately or delayed until culture results are known. If treatment is started presumptively, it should be stopped if cultures are negative. Follow-up throat cultures are not done routinely. They are useful in patients with multiple GABHS recurrences or if pharyngitis spreads to close contacts at home or school.

Tonsillectomy: Tonsillectomy should be considered if GABHS tonsillitis recurs repeatedly (> 6 episodes/yr, > 4 episodes/yr for 2 yr, > 3 episodes/yr for 3 yr) or if acute infection is severe and persistent despite antibiotics. Other criteria for tonsillectomy include obstructive sleep disorder, recurrent peritonsillar abscess, and suspicion of cancer.

Numerous effective surgical techniques are used to perform tonsillectomy, including electrocautery, microdebrider, radiofrequency coblation, and sharp dissection. Significant intraoperative or postoperative bleeding occurs in < 2% of patients, usually within 24 h of surgery or after 7 days, when the eschar detaches. Patients with bleeding should go to the hospital. If bleeding continues on arrival, patients generally are examined in the operating room, and hemostasis is obtained. Any clot present in the tonsillar fossa is removed, and patients are observed for 24 h. Postoperative IV rehydration is necessary in ≤ 3% of patients, possibly in fewer patients with use of optimal preoperative hydration, perioperative antibiotics, analgesics, and corticosteroids. Postoperative airway obstruction occurs most frequently in children < 2 yr who have preexisting severe obstructive sleep disorders and in patients who are morbidly obese or have neurologic disorders, craniofacial anomalies, or significant preoperative obstructive sleep apnea. Complications are generally more common and serious among adults.

INTRODUCTION- I

Acute tonsillopharyngitis is an inflammatory process of the

oropharynx. It can become a particularly horrible throat infection

involving Mycoplasma pneumoniae and Chlamydia pneumoniae

organisms that often occur in children. It can also come to pass in

patients who are given antibiotics for simpler infectins and founder

to take the prescribed regimen (dose and time).

Viruses

The adenoviruses are the most common cause of tonsillopharyngitis,

especially types 1, 2, 3, and 5, which are the types that infect small children

Page 4: Tonsil Lo Pharyngitis is Acute Infection of the Pharynx

most frequently. Other respiratory viruses are less common causes of

tonsillitis; the parainfluenza viruses probably are the most frequently isolated

in this group. Herpes simplex virus also is recognized as an occasional cause

of tonsillopharyngitis, as is Epstein-Barr virus. The most frequent causes of

the common cold, the rhinoviruses and coronaviruses, involve the tonsils.

Bacteria. Group A Streptococcus is the most important and frequent cause

of tonsillopharyngitis. It is frequently associated with acute rheumatic fever

and acute glomerulonephritis. Appropriate treatment of streptococcal

pharyngotonsillitis prevents the occurrence of rheumatic fever.

Epidemiology

Prevalence. The average incidence of all acute URIs is five to seven per

child per year. It is estimated that children have one streptococcal infection

every 4 to 5 years. Group A streptococci is isolated in 30-36.8% of children

with pharyngitis.

Age Occurrence. Pharyngitis is infrequent in the first 2 years of life, when

all URIs are most frequent. Most cases of pharyngitis occur in school-age

children, when the incidence of all infections is still high but less than in the

first 2 years.

Etiology

Viruses are isolated in about 50% of children less than 2 years old but

infrequently after that.

Group A streptococcus is isolated most frequently in school-age children,

while M pneumoniae is most often in teenagers.

Contact

All respiratory agents are spread by close contact or large droplets, with the

Page 5: Tonsil Lo Pharyngitis is Acute Infection of the Pharynx

exception of influenza, which also is spread by small droplets and the

airborne route.

A history of a household, school, or outside contact with another patient who

has tonsillopharyngitis due to a known agent, especially the group A

Streptococcus, increases the likelihood that the index infection has the same

etiology.

ANATOMY AND PHYSIOLOGY- III

The upper respiratory tract primarily refers to the parts of the respiratory

system lying outside of the thorax or above the sternal angle. Another

definition commomly used in medicine is the airway above the glottis or

vocal cords. Some specify that the glottis (vocal cords) is the defining line

between the upper and lower respiratory tracts; yet even others make the

line at the cricoid cartilage..

Upper respiratory tract infections are amongst the most common infections

in the world.

Picture:::::::::

NOSE: Physically a nose is an organ on the face. Anatomically, a nose is a

protuberance in vertebrates that houses the nostrils, or nares, which admit

and expel air for respiration in conjunction with the mouth. Behind the nose

is the olfactory mucosa and the sinuses. Behind the nasal cavity, air next

passes through the pharynx, shared with the digestive system, and then into

the rest of the respiratory system. In humans, the nose is located centrally

on the face; on most other mammals, it is on the upper tip of the snout.

NASAL CAVITY: A large fluid filled space above and behind the nose in the

middle of the face.

Page 6: Tonsil Lo Pharyngitis is Acute Infection of the Pharynx

PHARYNX: The part of the neck and throat situated immediately posterior

to (behind) the mouth and nasal cavity, and cranial, or superior, to the

esophagus, larynx, and trachea.

NASOPHARYNX: The uppermost part of the pharynx. It extends from the

base of the skull to the upper surface of the soft palate; it differs from the

oral and laryngeal parts of the pharynx in that its cavity always remains

patent (open).

OROPHARYNX: Reaches from the Uvula to the level of the hyoid bone. It

opens anteriorly, through the isthmus faucium, into the mouth, while in its

lateral wall, between the two palatine arches, is the palatine tonsil.

LARYNX: Commonly called the voice box, is an organ in the neck of

mammals involved in protecting the trachea and sound production. It

manipulates pitch and volume. The larynx houses the vocal folds, which are

an essential component of phonation. The vocal folds are situated just below

where the tract of the pharynx splits into the trachea and the esophagus

Sensitivity 80 - 90% (does NOT rule out) Xrays: obliteration of vallecula, swellin of arytenoids and aryepiglotticfolds, edema of prevertebral and retropharyngeal soft tissues,“ballooning”of the hypopharynx and mesopharynx, edematous thumbshaped epiglottis (Epiglottis > 8mm or Aryepiglottic fold > 7mm) Direct laryngoscopy indicated if suspecting and Xrays normalMANAGEMENT Expect sudden, unpredictable airway obstruction Minimize stimulation, have airway equipment by the bed, have cric tray at bedside, notifyOR and consult ENT emergently if airway compromise present or expected Hands off and transfer to OR for definitive airway management if at all possible If airway obstructs in ED: try orotracheal, could try LMA, be set up and ready for TTV orcricothyrotomy Safety and efficacy of Orotracheal and laryngoscopic guided nasotracheal intubationreported Blind nasotracheal intubation may lead to airway obstruction and is contraindicated Lateral neck Xray (portable) may be helpful but don’t waste time to OR Start antibiotics ASAP: cefuroxime, ceftriaxone, cefotaxime ? role for steroids and racemic epinephrine Disposition Mild cases: mild swelling on laryngoscopy without drooling, stridor, orrespiratory distress --------> ICU for treatment and monitoring withoutintubation Moderate/Severe: to OR for intubation, to ICU So who needs intubation? Alert, stable, not tiring, no resp distress can bemonitored Complications Meningitis, RPA, pneumothorax, empyema, pneumonia, sepsis, ARDS,pulmonary edema

DEEP SPACE INFECTIONS OF THELOWER FACE AND NECK Deep space infection of neck are dangerous and require rapid treatment Much less common because of dental hygeine and antibiotics Distorted airway anatomy = difficult airway Paralytics may cause muscular laxity and worsen the degree of airway obstruction Fiberoptic intubation useful BNI can cause abscess rupture, airway damage, further compromise Submandibular space: conglomerate of the sublingual and submaxillary spaces whichclinically function as a single space Sumandibular space is involved in Ludwig’s angina Five clinically relevant potential spaces in neck (figure 70-4) Peritonsillar space Parapharyngeal space: carotid, jugular vein, CN IX –> XII, sympathetics Retropharyngeal space: lies in the midline, medial to the parapharyngealspace and extends from the base of the skull to the superior mediastinumat the level of T2; superior constrictor muscle adheres to the prevertebralfascia and forms a raphe in the medial aspect ot the retropharyngeal

Definition

Pharyngitis is the swelling and inflammation of the pharynx. The pharynx is the back of the throat, including the back of the tongue. Tonsillopharyngitis is the swelling of the pharynx and the tonsils. The tonsils are soft tissue that make up part of the throat's immune defenses. Both pharyngitis and tonsillopharyngitis are commonly called a sore throat. Sore throats can easily be treated. If you have a sore throat for more than two days, contact your doctor.

Sore Throat Due to Inflammation

Causes

Many things can cause pharyngitis and tonsillopharyngitis. Causes include:

o Infection with a virus, such as the viruses that cause influenza (the flu) and the common coldo Infection with bacteria, such as the bacteria that cause strep throat

o Mucus from your sinuses that drains into your throat

o Smoking

o Breathing polluted air

o Drinking alcoholic beverages

o Hay fever  or other allergies

o Acid reflux  from the stomach

o Allergies

o Food debris collecting in small pockets in the tonsils

o Infectious mononucleosis

Risk Factors

A risk factor is something that increases your chance of getting a disease or condition. Almost everyone will get a sore throat. These risk factors increase your chance of getting a sore throat:

o Age: children and teens, and people aged 65 or oldero Exposure to someone with a sore throat or any other infection involving the throat, nose, or ears

o Situations that cause stress, such as traveling, working, or living in close contact with people

Page 34: Tonsil Lo Pharyngitis is Acute Infection of the Pharynx

o Exposure to cigarette smoke, toxic fumes, industrial smoke, and other air pollutants

o Having other medical conditions that affect your immune system, such as AIDS or cancer

o Stress

o Hay fever or other allergies

Symptoms

Your symptoms depend on the cause of the condition. If you experience any of these symptoms, do not assume it is due to pharyngitis or tonsillopharyngitis. These symptoms may be caused by other health conditions. If you experience any one of them, see your doctor.

Symptoms include:

o Sore throato Pain or difficulty when swallowing

o Difficulty breathing

o Fever

o Enlarged lymph nodes in your neck

Diagnosis

The doctor will perform a physical exam, looking closely at your mouth, throat, nose, ears, and the lymph nodes in your neck.

o This physical exam may include:o Using a small instrument to look inside the nose, ears, and mouth

o Gently touching the lymph nodes (glands) in your neck to check for swelling

o Taking your temperature

o Examining your ears
