Insecticidal activity of common reagents for insect foreign bodies of the ear Antonelli PJ, Ahmadi A, Prevatt A, Laryngoscope. 2001;111:15-20 Conclusion: Many agents commonly available in the EMS may be used to kill insect foreign bodies in the ear canal. Antiseptic agents and microscope oil were the most effective against the most common insect foreign body, the cockroach. Ticks were the most resistant to all agents tested. Comment: What is the best agent to grab when you have a distraught patient severely agitated by the presence of a live insect in the ear? Mineral oil has been commonly recommended, but it tends to create a gooey mess, making foreign body removal more difficult. Isopropyl alcohol would be my drug of choice. Although it is only number 2 on the quick-kill list, it is probably more readily available than the number 1ranked ethyl alcohol. Liquid anesthetics are a nice thought, but take at least 3 or 4 times longer to achieve the desired lethal effect on the bug. (From ACEP)

Greater understanding and visualization of nasal anatomy revealed that the nose receives blood from many different sources and a large amount of vascular redundancy exists. The external carotid artery divides into the maxillary and superficial temporal arteries. The maxillary artery has many branches including the sphenopalatine artery. The sphenopalatine artery emerges from the sphenopalatine foramen and further divides into four branches: the posterior septal, inferior turbinate, middle turbinate, and nasopalatine arteries. The inferior and middle turbinate arteries depart from the sphenopalatine artery at right angles. Through its four divisions, the sphenopalatine artery supplies the majority of the blood to the nose (43). The sphenopalatine infuses the posterior aspect of the nose, the septum, and the lateral wall from the middle turbinate caudally. In the anterior region of the septum at about the same level as the middle turbinate is Littles area and within it is Kiesselbachs plexus, a area of vascular anastomosis that is often the site of anterior epistaxis.(Emedhome.com)

THE DIFFERENTIAL DIAGNOSIS OF PARADOXICAL VOCAL CORD MOVEMENT
Jamie Koufman, MD
This article is reprinted from THE VISIBLE VOICE Vol. 3, No. 3. (July 1994).
Paradoxical vocal cord movement (PVCM) producing airway obstruction is a relatively uncommon, and sometimes confusing, condition that affects the larynx. PVCM occurs when there is inappropriate closure of the vocal cords during inhalation, and the resultant respiratory obstruction may be intermittent or continuous, mild or severe, depending on the cause. The differential diagnosis of PVCM also includes congenital, inflammatory, traumatic, neoplastic, and neurological causes. Contrary to popular belief, relatively few cases are “functional,” i.e., psychogenic. This article presents the clinician with a differential diagnosis for PVCM and the clinical features that differentiate its various causes.
During the respiratory cycle of most higher animals and of human beings, the vocal cords partially abduct (open) with inhalation and partially adduct (close) with exhalation. This phasic vocal cord movement is physiologic, and it allows the unimpeded movement of air into the lungs during inspiration while helping to maintain the alveolar patency (of the lungs) by providing positive airway pressure during expiration. Thus, the larynx serves as an upper airway valve to help keep the lungs expanded.
Some patients who present with stridor (noisy breathing), dyspnea (difficulty breathing), and upper airway obstruction have paradoxical vocal cord movement (PVCM), characterized by inappropriate adduction (closure) of the vocal cords during inhalation. The persistence and the degree of inappropriate glottic closure determines the degree of the airway obstruction, and hence the severity of respiratory symptoms experienced by the patient. In some patients, the problem is constant and severe, requiring prompt remedial treatment, and in other patients, the problem is intermittent and relatively mild. Few articles1,2 address the differential diagnosis of this condition or provide an approach to the management of these challenging patients.
The differential diagnosis of PVCM is shown in Table 1. Three key elements of the history quickly limit the possibilities in each case: (1) Is the stridor constant or intermittent? (2) Is there any history of head trauma, stroke, or other brainstem problem? (3) Are there any other associated symptoms, such as hoarseness, dysphagia, globus pharyngeus, or cough? In addition, as discussed below, the findings on fiberoptic laryngeal examination are crucial in making the diagnosis.
TABLE 1: PARADOXICAL VOCAL FOLD MOVEMENT (DIFFERENTIAL DIAGNOSIS)

- Respiratory-type laryngeal dystonia
- Drug-induced laryngeal dystonic reactions

Paroxysmal Laryngospasm and PVCM Due to Gastroesophageal Reflux Gastroesophageal reflux can cause a true intermittent type of PVCM, laryngospasm, or both, in which adduction predominates and abduction is temporarily lost during “attacks.”3-5 Thus, laryngospasm may be considered a specific variation of PVCM. Using this definition, reflux appears to be the most common cause of PVCM.5 In either case, the attacks of respiratory obstruction are paroxysmal and the result of direct contact of gastric fluids with laryngopharyngeal structures.5 It is postulated that some additional form of vagal dysfunction may prolong the episodes for minutes, hours, or sometimes days.6,7
Patients with this frightening condition describe intermittent, sudden-onset, noisy, obstructed breathing, which some describe as “choking episodes.” Attacks of stridor may follow a pattern, e.g., occurring after a meal, after the start of exercise, or after bending over. Sometimes, the attacks may awake the patient from sound sleep. Often, the attacks are truly paroxysmal, occurring without any pattern or identifiable precipitating events. Some patients have one or more attacks per day, and others have their attacks as infrequently as a few each year. The duration of attacks is variable, but “a few minutes” is typical.5
Two-thirds of the patients deny ever having heartburn; however, all complain of some other symptom(s) of laryngopharyngeal reflux, such as chronic or intermittent hoarseness, difficulty swallowing, a sensation of a lump in the throat, chronic throat clearing and cough, or simply too much throat mucus and/or “post-nasal drip.”5
Within the past two years, the author has diagnosed this condition in 15 adult patients.5 Of these, 12 underwent pH monitoring, which yielded abnormal findings in 11 (92%), five of whom had laryngopharyngeal reflux demonstrated by a pH probe in the hypopharynx behind the laryngeal inlet.5 All fifteen patients were treated with dietary and life-style modification as well as omeprazole 20 mg b.i.d., and, within four weeks, all attacks of laryngospasm had ceased in all patients.
H2-blockers appear to be inadequate treatment for reflux in this group of patients.5,8 For some patients under age 40 years, fundoplication should be considered as an alternative long-term treatment after the symptoms of laryngospasm have been initially corrected by omeprazole therapy; that is, antireflux surgery should be considered in patients who subsequently fail maintenance on H2 blocker therapy.5,8
Patients with the respiratory type of adductor laryngeal dystonia (discussed below), may also have reflux disease. When these two conditions occur together, the attacks of PVCM tend to be prolonged and severe, and the patient may require airway intervention, e.g. intubation or tracheotomy. Such a patient usually requires treatment with both botulinum toxin and omeprazole.
The clinician caring for patients with PVCM due to causes other that reflux should realize that reflux may be a secondary initiating or complicating factor. When laryngopharyngeal reflux is suspected, by the history or by the laryngeal findings, ambulatory 24-hour double-probe pH monitoring is indicated. Long-term medical treatment or surgical fundoplication is usually necessary in such patients.
After reflux, psychogenic stridor appears to be the second most common cause of PVCM. (The author sees approximately 2 to 3 such cases each year.) Usually, this group of patients is easily diagnosed. First, almost all are teenagers. Second, PVCM occurs with a sudden onset and offset. Third, such patients are usually unconcerned (blase) about their noisy breathing and airway obstruction. Fourth, it is usual for the clinician to be able to “fool” the patient during fiberoptic examination, thus making the PVCM go away. (In most cases, when the patient is asked to read a long passage loudly, the stridor may disappear and phasic respiratory activity of the vocal cords may become normal.) Fifth, the PVCM attacks often can be precipitated and ameliorated by injections of placebo.9-13
The history of each patient will often suggest an underlying psychologic or psychiatric problem, manipulative behavior, and family problems, alone or in various combinations, and the stridor usually occurs at “times of significance” for the patient. In one patient, for example, the stridor only occurred when she was sent to the school principal’s office for misbehaving. Characteristically, her stridor was so loud and disturbing that it demanded medical attention.
A word of caution about this diagnosis. Even though the criteria for psychogenic stridor are fairly well-established — (1) periods of normal phasic vocal cord movement during the fiberoptic examination, (2) induction of stridor and response to placebo, and (3) a psychological or psychiatric disorder — still, this is almost a diagnosis of exclusion. A review of the literature makes clear that many cases of “psychogenic stridor” probably actually had an organic basis, e.g., reflux or dystonia.
Patients with presumed psychogenic PVCM should be approached by the otolaryngologist and the psychologist and/or psychiatrist as a team, and should be completely evaluated before the team reaches a final diagnosis.
In the author’s experience, none of the patients diagnosed as having psychogenic stridor have subsequently developed one of the other conditions associated with PVCM. On the other hand, patients with another presumed cause of PVCM, such as respiratory-type laryngeal dystonia, are sometimes eventually diagnosed as having psychogenic stridor. In other words, the differentiation between dystonia-related and psychogenic PVCM sometimes may be difficult.
Respiratory-Type Adductor Laryngeal Dystonia The most common type of focal laryngeal dystonia causes a voice disorder known as spasmodic dysphonia (SD). SD occurs in women five times more frequently than in men, is rarely seen in people under age 20 years, and usually affects the voice very severely, but does not affect respiration. The most common pattern is the adductor type, in which glottal overclosures create a “strain-strangled” sounding voice. Patients with this type of SD do not usually experience difficulty breathing, although some patients with severe non-focal dystonia involving the larynx and pharynx (Meige’s syndrome) do have severe, inappropriate laryngeal hyperadduction, which causes airway obstruction. There also is a small group of patients with a respiratory type of adductor laryngeal dystonia in whom the vocal cords inappropriately hyperadduct during inspiration but the voice is normal. Stridor in these patients is present throughout the day, but disappears during sleep, a characteristic of most dystonias.
Blitzer and Brin 14 reported a large series of patients with laryngeal dystonia, most of whom had the well-recognized adductor-type SD. However, they did report that approximately 1% had a respiratory type of adductor laryngeal dystonia, as described above.
Within the past five years, the author has seen five patients with this type of laryngeal dystonia; these patients represent 2% of the author’s laryngeal dystonia patient population.15 None of the five have significant abnormality of voice, but two actually presented with tracheotomy tubes in place.15 On fiberoptic examination, the vocal cords characteristically close during inspiration, and when the patient is asked “take a deep breath,” the degree of overclosure worsens, increasing the respiratory obstruction.
Of the five patients in the author’s series, all have responded well to treatment with botulinum toxin, although this group of patients appears to need larger doses of botulinum toxin than those required by typical SD patients.15
Drug-Induced Laryngeal Dystonic Reactions
Temporary drug-induced PVCM has been reported after administration of neuroleptic drugs, including chlorpromazine and haloperidol.16 (Obviously, this cause of PVCM needs to be considered only in patients receiving such medications.) The stridor is usually associated with extrapyramidal symptoms, muscle stiffness, and dystonias of the head and neck, e.g., torticollis. The airway obstruction (PVCM) and the other dystonias are relatively short-lived (hours), and are reversible with intravenous administration of an anticholinergic drug.16 (The author’s experience is in agreement with this report.)
Thiopental, an anesthetic, also may have some such effects at certain doses.17 This may explain the relatively high incidence of “laryngospasm” observed during the induction of anesthesia. It has been shown experimentally that such laryngospasm can be prevented by the administration of topical lidocaine.18
Asthma-Associated Laryngeal Dysfunction
Patients who present with PVCM are frequently misdiagnosed as having asthma as the cause of the airway obstruction, even though anti-asthma medications are ineffective. Nevertheless, there appears to be a subset of patients with asthma who also have PVCM.19 Although the mechanism of PVCM in these patients is unknown, glottal aperture changes have been observed in asthma patients20; and vagal reflex dysfunction may be the cause.20 In any asthma patient, when inspiratory stridor is present, the diagnosis of PVCM should be considered. The finding of PVCM on transnasal fiberoptic laryngoscopy is diagnostic.
Many central neurological (usually brainstem) abnormalities can cause PVCM, in addition to or complicated by bilateral abductor paralysis, apneic episodes, and central sleep apnea syndrome.21 23 Severe closed head injury, Chiari malformations I and II, meningomyelocele, and cerebrovascular accidents (strokes of the posterior circulation) may all produce PVCM. In these cases, the obstruction and inappropriate vocal cord movement may be inconsistent and variable, and may appear to change with multiple fiberoptic examinations; what is important, however, is that the stridor does not disappear during sleep. This point is critical, since with all the other causes of PVCM, the stridor is paroxysmal or improves during sleep. Early (days or weeks) after closed head injury, extubation may fail and the patient may require multiple intubations, and then, later on, a tracheotomy. With time, as the cerebral and brainstem edema subsides, the vocal cord movement may return to normal and the stridor will disappear. Similarly, some patients with congenital lesions of the brainstem may experience a normalization of vocal cord function after surgical treatment of the lesion.
In the evaluation of patients with PVCM due to brainstem abnormalities, computerized tomographic scanning, magnetic resonance imaging (or both), as well as neurologic consultation is recommended. The prognosis should be guarded. For instance, patients with Chiari malformations who undergo surgical treatment of the malformation may have improvement of their PVCM postoperatively, while others may require a permanent tracheotomy.
APPROACH TO THE PATIENT WITH PVCM
After a thorough history is obtained, the first examination of the stridulous patient should include transnasal fiberoptic laryngoscopy (TFL). During this examination, the patient should be asked to: (1) alternatively phonate the vowel /i/ and sniff, in rapid alternating succession; (2) take deep breaths; (3) cough, throat clear, and chuckle; (4) count to fifty, rapidly and loudly; (5) read a written passage in a loud voice; and (6) sing.
These maneuvers may reveal a pattern of adduction and abduction consistent with PVCM and a specific diagnosis. Patients with an organic cause of the PVCM, that is, a non-psychogenic cause, usually demonstrates consistent fiberoptic findings, whereas patients with psychogenic PVCM do not. Patients with psychogenic stridor, for example, will often revert to normal phasic vocal cord movement when asked to count or read out loud.
PVCM is therefore usually diagnosed by TFL, and the diagnosis should be considered when there are findings of: (1) inappropriate vocal fold adduction during inspiration; (2) paroxysmal inability to abduct the vocal cords (“transient abductor paralysis”); or (3) a combination of these findings. There is, however, one group of patients that comprises a notable exception: patients with reflux-induced paroxysmal laryngospasm may have normal phasic vocal fold movement on TFL. In these patients, other findings characteristic of laryngopharyngeal reflux (edema, erythema, posterior commissure hypertrophy, and granulation) are almost always observed.
A firm diagnosis of reflux-induced PVCM can be made when the history (pattern and associated symptoms), the laryngeal findings, and the pH monitoring data all support the diagnosis. In addition, complete resolution of the laryngospastic episodes during a therapeutic trial of omeprazole (20 mg b.i.d.) confirms of the diagnosis.
Unlike patients in the other PVCM groups, patients with respiratory-type laryngeal dystonia describe a progressive onset of the PVCM over a period of days, weeks, or months. In addition, such patients usually deny having hoarseness or other reflux symptoms. On TFL, their PVCM is consistent and worsens when the patient is asked to take a deep breath, although the PVCM may improve when the patient reads a written passage or sings. However, improvement is only partial and transient.
On occasion, differentiating dystonic from psychogenic PVCM can be a difficult task. When the clinician is faced with this diagnostic dilemma, neuropsychological testing, psychiatric consultation, and trial injections of botulinum toxin may all be indicated. In some cases, it may take months for the clinical team to reach a diagnosis.
Except for patients in the brainstem abnormality group (who often require tracheotomy), patients with PVCM usually do not have respiratory obstruction severe enough to warrant emergency airway intervention. Of the other groups of patients with PVCM, dystonia patients appear next in terms of the frequency of need for airway support, followed in decreasing order by the psychogenic group, the asthma group, and the reflux group. Table 2 summarizes some of the differentiating features of PVCM.
The diagnostic work-up for each patient with PVCM should be individualized and may include some or all of the following: serial fiberoptic examinations, pH monitoring, neuropsychiatric evaluation, placebo injections, audio-recordings of the patient’s breathing during sleep, and radiographic examinations. In selected cases, therapeutic trials of omeprazole and/or laryngeal injections of botulinum toxin also may be used.
Finally, PVCM can be confused with other causes of laryngeal obstruction, at least on the initial clinical examination. Inspiratory stridor, for example, may be seen in patients with bilateral vocal cord paralysis, and in patients with laryngeal stenosis or fixation. These conditions may be differentiated from PVCM because, in the former group of conditions, examination shows that vocal cord abduction does not occur. Although abduction may be inconsistent, inappropriate, or incomplete, it must occur some of the time in order for the diagnosis of PVCM to be made.
TABLE 2 SOME DIFFERENTIATING FEATURES OF THE CAUSESOF PARADOXICAL VOCAL CORD MOVEMENT
Airway Support Needed
PVCM presents the clinician with an interesting and challenging differential diagnosis. Only abnormalities of the brainstem produce a constant (day and night) stridor and respiratory obstruction, whereas all of the other causes are intermittent or occur only during the daytime. The causes of PVCM, in the author’s experience, in order of frequency of occurrence are: gastroesophageal reflux, followed by psychogenic stridor, respiratory-type laryngeal dystonia, and abnormalities of the brainstem. In the last group, closed head injuries are most common.
The work-up of PVCM may require a multidisciplinary approach and a variety of diagnostic methods. Likewise, treatment often must be individualized. Jamie Koufman, M.D.

Negative rapid strep and worsening pharyngitis raises an interesting differential diagnosis. Remember that the rapid strep test only has a sensitivity of 80-90%. Sometimes we do not get an adequate throat swab. Sometimes we have sampling error. So a negative rapid test does not eliminate group A strep as a possibility.
Next, consider the non-group A strep – groups C and G. In adolescents they cause approximately 1/3 as many sore throats as group A strep (this is not true for pre-adolescents.
Always consider infectious mononucleosis in adolescents with worsening pharyngitis. Also remember that acute HIV infection can present as a sore throat.
Finally, we must consider peritonsillar abscess and Lemierres. We should get clues from a careful physical examination. We should examine the patient for neck swelling or asymmetric tonsillar swelling.
The key point is patient education. We should tell patients that if they are worsening in 3-5 days that we should re-examine them, perhaps do further testing and generally view the patient as having a potentially serious infection.

Ducic and colleagues described the vallecula sign, which is easily learned and applied by practitioners at all levels of training [ix]. In this prospective, blinded study involving 26 laryngoscopically-proven cases of epiglottitis and 26 controls, staff emergency physicians, radiology and otolaryngology residents, and senior medical students were asked to evaluate randomly mixed radiographs for epiglottitis, both before and after a 5-minute tutorial on the vallecula sign. The sign increased sensitivity and specificity from 78.5% and 82.8% to 98.2% and 99.5% respectively, with no difference between evaluator groups. This sign is based on evaluating the vallecula, which appears as an air pocket at the level of the hyoid that should be roughly parallel to the pharyngotracheal air column. To do this, first start at the base of the tongue, trace down to the hyoid bone where you should then find the epiglottis. If the air column anterior to this is not deep, sharp, and roughly parallel to the pharyngotracheal air column, then epiglottitis is present. In this study, the vallecula was deemed abnormal in all cases of epiglottitis, including those patients with minor symptoms, as well as those that needed urgent airway intervention. Furthermore, the vallecula was deemed abnormal in cases where the epiglottis itself was difficult to evaluate (and hence signs like the thumb sign could not be applied). A normal appearing vallecula accurately predicted a normal epiglottis (see Figure 4 below of a normal vallecula and an abnormal vallecula found with epiglottitis, both outlined in red). It is noted that the x-ray must be taken with the patients mouth closed, as an open mouth may artificially obliterate the vallecula by epiglottic repositioning.

Step 1: Ensure that the patients mouth is closed for x-ray. Step 2: Identify the base of the tongue. Step 3: Trace the tongue to the level of the hyoid. Step 4: Locate the epiglottis. Step 5: Locate the air pocket extending nearly to the hyoid. Is the vallecula deep and roughly parallel to the pharyngotracheal air column? YES: No epiglottitis NO: Epiglottitis present

Most readers know that I have written extensively about pharyngitis. After yesterday’s brief post about a letter I wrote, I received this comment:
so how should a culture be sent, just culture for any species? Our lab does STREP A culture only for throat/tonsil swabs.
Here are the problems for adolescent and adult pharyngitis (caveat pre-adolescents are different in many ways so this rant only focuses on adolescents and adults):
- The Group A strep rapid tests probably only have a sensitivity of around 75% in actual practice this makes reliance on rapid tests less certain than most experts have suggested. Fortunately the specificity is very high, so we can really believe positives but not negatives.
- Group C (and group G) cause approximately 1/3 as many sore throats as group A but I would favor treating those infections. Some labs will culture for these infections, but most only culture for group A.
- Fusobacterium necrophorum probably causes approximately 10% of pharyngitis in this age group. We cannot currently test for this infection.
- All these bacterial infections can cause serious sequelae.
So what is a conscientious clinician to do? I have favored the empiric therapy approach for those patients who look sick. I define looking sick as pharyngitis scores of 3 or 4 (I am still embarrassed to type the eponym).
I tell all patients that they should be improved in 3-5 days. If their symptoms worsen or if they develop neck swelling they should return for further evaluation.
And that’s my story and I am stickin

Microbes associated with Ludwigs angina
Involvement of the sublingual space may result in elevation of the tongue. Clinically, involvement of this space may be excluded by asking the patient to protrude the tongue past the vermillion border of the upper lip. The patients ability to perform this test safely excludes the likelihood of sublingual space compromise (Flynn TR. The Swollen Face: Severe Odontogenic Infections. Emerg Med Clin North Am. August 2000; 18 (3): 481-519)

Local extension of oropharyngeal infections such as tonsillitis, pharyngitis, or adenitis in children can lead to retropharyngeal lymph node infection. These infections may progress from cellulitis to phlegmon and finally to retropharyngeal abscess (RPA), which requires drainage. Abscesses in the retropharyngeal or prevertebral spaces are collectively known as RPA. As the retropharyngeal lymph nodes typically regress by age 4 to 6, the main cause of RPA in older children and adults is either extension of odontogenic infection or local trauma (as with a fish bone or holding an object in the mouth). Patients with an RPA may present with symptoms and signs similar to that of acute epiglottitis, including dysphagia, odynophagia, hoarse voice, fever, and neck extension or unusual positioning. Unlike the tripod positioning common in epiglottitis, patients with RPA often lay flat with their neck held in extension. When severe, there may be enough local swelling and pharyngeal pain to cause reluctance in swallowing solids, liquids or secretions, which therefore leads to drooling
The lateral soft tissue neck x-ray may suggest the diagnosis of RPA. Look for soft-tissue swelling in the retropharyngeal space or retrotracheal space, with the limits described below:
Soft Tissue Measurements
Retropharyngeal space (measured at C2) < 7mm Retrotracheal space (measured at C6)
< 22mm (adults) < 14mm (children < 15 years)
The retropharyngeal space is measured from the anteroinferior aspect of C2 to the posterior pharyngeal wall, and should not exceed 7mm in children or adults. The retrotracheal space, measured from the anteroinferior aspect of C6 to the posterior pharyngeal wall, should not exceed 22mm in adults or 14mm in children. The most reliable x-rays are taken during deep inspiration with the neck extended. Films taken during expiration (particularly in children less than 24 months) or that are rotated can increase the apparent width of neck soft tissues.

The classic Lemierre’s syndrome has been characterizedby four findings: a primary infection of the oropharynx, septicemiadocumented by at least one positive blood culture, clinicalor radiographic evidence of thrombosis of the internal jugularvein, and at least one metastatic focus of infection.3 Patientstypically present with a history of tonsillitis for severaldays, persistent fever, neck pain, and general malaise, followedby signs of sepsissymptoms that are all present in thiscase. Delays in diagnosis are common because of a low indexof suspicion probably due to its rarity or to atypical prodromes.4 The key to diagnosis is to have a high level of suspicion in older children and adolescents who have fever and neck painor swelling after pharyngitis or tonsillitis.5 Abnormal radiographswith evidence of infiltrates, pleural effusions, and embolicphenomena are common, but normal findings do not exclude thediagnosis.5,6 Diagnosis is confirmed by demonstrating phlebitisof the internal jugular vein.5 The proposed pathogenesis inthis case is as follows: disruption of the mucosal barrier of the oropharynx leads to hypoxia and tissue destruction, whichcreates the oxygen-free environment necessary to maintain thelow oxidation-reduction potential necessary for bacterial proliferation.5 The anatomy of the lateral pharyngeal space (an inverted cone extending from the base of the skull to the hyoid bone bounded medially by the superior pharyngeal constrictor and laterallyby the medial pterygoid) allows invasion of the internal jugularvein either by direct extension or by lymphatic or hematogenousspread from the peritonsillar vessels.7
By rcentor on Medical Rants
Despite finishing my residency in 1978 and writing many papers about strep pharyngitis, I first heard of Lemierres syndrome in the late 1990s. During my training, I suspect the incidence of Lemierres syndrome was extremely low. As I slowly became more aware of Lemierres syndrome, I started to put this disease into context.
In 2002, during the early days of this blog, I wrote this rant – Some sore throats are VERY serious.
Very interesting story appears on the BBC site – Warning over killer throat disease. I have done sore throat research early in my career. This article describes a condition so unusual that I know little about it.
It follows a significant rise in the number of cases of Lemierres disease this year.
The disease, which is most common in young adults, can cause serious illness and even death if left untreated.
With this disease patients can go downhill quite quickly
The disease is cause by a bacterium called Fusobacterium necrophorum that normally lives harmlessly in peoples mouths.
However, for reasons unknown to scientists, it can start to attack the body of previously healthy people.
It mostly affects young people between the ages of 16 and 23 and is more common in men.
The disease is rare and affects just a handful of people each year. However, there have been 30 cases so far this year – as much as the total for all of last year.
Most viral sore throats get better of their own accord in a few days but with this disease patients can go downhill quite quickly.
Lemierres disease starts off as a very sore throat and leads to a fever, swollen glands and a general feeling of being unwell.
For the past 30 years, the infectious disease community has worked to decrease the use of unnecessary antibiotics. They have assumed that group A beta hemolytic streptococcal infection is the only pharyngitis cause which needs necessary antibiotics. They have assumed that group C and group G streptococci do not need antibiotics. They have excluded the possibility of unknown bacterial infections. Now it appears that Fusobacterium necrophorum may indeed be an unknown bacterial cause of pharyngitis.
The problem with Lemierres Disease is that it represents a long tail disease. Most sore throats are viral or due to streptococcal disease. At least we thought that until recently. Evidence from 2005 in two articles suggests that the organism thought responsible for most Lemierres Disease – Fusobacterium necrophorum – may cause as much as 10% of pharyngitis.
Hagelskjær Kristensen L, Prag J. Lemierres syndrome and other disseminated Fusobacterium necrophorum infections in Denmark: a prospective epidemiological and clinical survey. European Journal of Clinical Microbiology & Infectious Diseases 2008; 779-789.
Finally we had an epidemiologic study which defined the extent of this disease. I have extrapolated the Danish data to the United States. Assuming the same incidence, I estimate that we have approximately 1000 patients with Lemierres yearly and 100 deaths. I would put the confidence range of these estimates at 50% greater or less than this estimate.
So Lemierres is truly an orphan disease if you just look at the numbers. We have some advantages though in attacking this disease. Routine antibiotics can treat this syndrome very well. We do not need new drugs.
As readers know, I gave my new Grand Rounds presentation on Adult Pharyngitis: Morbidity and Mortality in late July. I am already scheduled to give this talk 4 more times (Oct and Nov.) I hope to find venues to present this talk much more over the next year or two.
My 2007 perspective on adult pharyngitis – Pharyngitis Management: Defining the Controversy – included this paragraph:
Another potential reason for antibiotic therapy for severe pharyngitis is to treat Fusobacterium necrophorum. Recent data suggest that these bacteria may cause endemic acute pharyngitis. F. necrophorum infections can cause Lemierres Disease, peritonsillar abscess and persistent sore throat symptoms. While we do not yet know the probability of progression to these complications, certainly empiric antibiotic treatment would likely decrease their incidence. A recent pediatric paper has documented the increasing incidence of F. necrophorum infections (including Lemierres Syndrome) over a recent 6-year period. The authors speculate that decreased empiric antibiotic use may be contributing to the resurgence of this infection.

Even bacterial sinusitis will self resolve if treated symptomatically so only treat severe sx.
in patients with sx of ~48 hrs with signs of bacterial sinusitis, there was no difference between treatment with augmentin or placebo (Arch Intern Med 2003;163:1793-1798)
5 clinical elements are predictive: maxillary toothache, poor response to decongestants, abnormal transillumination, colored nasal discharge, and purulent nasal mucus. When none are present, 9% had sinusitis, when all are rpesent 92% had sinusitis (Ann Intern Med 117:705, 1992)
Etiology: The microbiology of acute sphenoid sinusitis differs from that of uncomplicated maxillary sinusitis. Whereas maxillary sinusitis is caused predominantly by Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis, sphenoid sinusitis has a different profile. Gram-positive organisms predominate, with Staphylococcus aureus most common, followed by Streptococcus pneumoniae. Chronic sphenoid sinusitis can be caused by both gram-negative and gram-positive organisms, anaerobes, and mixed flora, which are more common. Fungal disease also must be considered, especially in the context of a patient who is immunocompromised. Pathophysiology: The pathophysiology of sphenoid sinusitis involves blockage of sinus ostia and impaired mucociliary clearance leading to stasis and secondary bacterial infection. Several predisposing factors have been implicated. Anatomic differences include variations in the position of the intersinus septum and small or abnormally placed ostia. Blunt, penetrating, or surgical trauma can alter drainage patterns as well as allow entry of pathogenic organisms. Swimming or diving with forceful water entry through the nose also has been implicated in causing disease. Immunosuppression due to long-term steroids, diabetes, or radiotherapy can predispose patients to this disease, as can obstruction of sinus ostia by polyps or tumor. Clinical: Patients with acute sphenoid sinusitis often present with vague nonlocalizing symptoms. Headache is the most common symptom; almost all patients in various studies complain of headache. Although the vertex headache is classic, the pain also can be retroorbital, parietooccipital, or frontal. In general, the headache is described as severe, interfering with sleep, and not relieved by narcotics. Fever and purulent rhinorrhea often are noted, and hypoesthesia of the trigeminal nerve may be present in select cases. Neurologic and ophthalmologic findings suggest impending complications. Decreased mental status, lethargy, and seizures point to intracranial extension or meningitis. Ophthalmologic findings may include abducens nerve palsy or hypoesthesia of V1 and/or V2. Chemosis, proptosis, ptosis, diplopia, or decreased visual acuity and ophthalmoplegia may be noted. Maintain a high index of suspicion for sphenoid sinusitis. A review by Hnatuk et al reported that 78% of cases of sphenoid sinusitis were initially misdiagnosed. Evaluate patients with severe progressive headache, with or without fever, for sphenoid sinusitis. Thoroughly investigate signs of orbital or neurologic complications. Disease in the sphenoid sinus is not always inflammatory in nature. Consider a broad differential diagnosis in a patient with clinical suggestion of sphenoid disease and imaging studies consistent with sphenoid opacification. Isolated sphenoid lesions, for example, merit special consideration. In his review of 132 cases of isolated sphenoid disease, Lawson found that, while inflammatory disease predominates, neoplasms, fibroosseous disease, and other entities were significant. In addition to acute and chronic sinusitis, inflammatory diseases included mucoceles, polyps, retention cysts, and fungal disease. Neoplasms included benign tumors, such as inverting papilloma, myxofibroma, plasmocytoma, and schwannoma. Salivary gland malignancies, such as adenoid cystic carcinoma and epidermoid carcinoma, were present, as well as malignancies including squamous cell, melanoma, and hemangiopericytoma. Extension from adjacent sites, such as the nasopharynx and pituitary, was noted, as was metastatic disease from the prostate, kidney, and tonsil. Several cases of fibrous dysplasia and ossifying fibroma were observed. Miscellaneous entities including foreign bodies, encephaloceles, and even an internal carotid aneurysm were also included. In general, although many clinical cases of sphenoid disease may be inflammatory in nature, consider other entities. INDICATIONS Section 3 of 10 Author Information Introduction Indications Relevant Anatomy And Contraindications Workup Treatment Complications Outcome And Prognosis Future And Controversies Bibliography In general, start medical treatment of acute sphenoid sinusitis once the diagnosis is made. Institute antibiotics and decongestants for 24 hours, and, if the patient does not improve over this time course, schedule surgical therapy. If the patient has evidence of complications, undertake urgent surgical decompression. Some individuals advocate early and aggressive surgical and medical treatment for acute sphenoid sinusitis. Hnatuk comments on the aggressive nature of the disease and concludes that nonoperative medical management is not indicated. These conclusions are based on a small number of patients, all in their teenage years. RELEVANT ANATOMY AND CONTRAINDICATIONS Section 4 of 10 Author Information Introduction Indications Relevant Anatomy And Contraindications Workup Treatment Complications Outcome And Prognosis Future And Controversies Bibliography Relevant Anatomy: The sphenoid sinus is the most posterior of the paranasal sinuses. It is a paired structure, divided asymmetrically by an intersinus septum. Pneumatization begins at age 3 years and progresses rapidly between ages 5 and 7 years. Various degrees of pneumatization exist. While the sphenoid most commonly is fully pneumatized, the structure can be only partially aerated or can be filled completely with bone. Pneumatization also may occur in the bones adjacent to the sinus, such as the greater wing of the sphenoid bone or the vomer or palatine bones. The anterior wall of the sphenoid is adjacent to the sphenoethmoidal recess. The floor of the sinus contributes to the roof of the nasopharynx. Posterior to the sphenoid is the clivus. The inferior aspect where it articulates with the vomer is known as the sphenoid rostrum. The pituitary gland sits superior to the sinus. The sphenoid ostium is membranous but surrounded by bone. It lies approximately 30° from the nasal floor and 7 cm from the nasal vestibule. Lateral to the sphenoid sinus lies the cavernous sinus. The close proximity of the sphenoid to the structures within the cavernous sinus accounts for much of the danger of acute sphenoiditis. Within the cavernous sinus lies the internal carotid artery as well as cranial nerves (CN) II, III, IV, and VI and V3. These structures may lie adjacent to the sphenoid and cause indentations within the wall. The internal carotid artery can be observed indenting the posteroinferior surface of the lateral wall. Cadaver studies have shown that the bony covering is thin in 71% of patients and absent in 4% of patients. The optic nerve also has a significant relationship to the sphenoid sinus. As the optic nerve travels within the optic canal, it passes over the anterolateral region of the sphenoid roof. The bony covering over the nerve has been noted to be absent in 4% of individualsBack to top
