Uvulitis and supraglottitis: early manifestations of Kawasaki disease

Isolated Uvulitis in a Patient After Smoking Fentanyl

Isolated uvulitis is a rare but potentially devastating condition that can result in airway compromise. Etiologies include infection, trauma, allergy, primary angioedema, immunologic disorders, and inhalation injury. Uvulitis has been previously reported as a reaction to inhalation of cannabis, crack cocaine, and mephedrone. We present a case of isolated uvulitis with concerns for impending airway obstruction in a patient after smoking fentanyl. While a sore throat is a common chief complaint among ED patients, emergency providers should consider uvulitis within this deadly differential.

Hoarseness as a presenting sign in children with Kawasaki disease

We noted that many patients with Kawasaki disease (KD) were hoarse at presentation and thus evaluated the frequency of hoarseness in children with acute KD. New onset hoarseness was noted in 86 of 287 (30%) prospectively assessed KD patients. Laryngoscopic examination of 3 hoarse patients with acute KD revealed edema and erythema of the larynx.

Retropharyngeal edema: an unusual manifestation of Kawasaki disease

BACKGROUND

Kawasaki disease (KD) is an acute multisystem vasculitis of unknown etiology that typically affects young children. KD presenting as a retropharyngeal inflammatory process is very rare.

OBJECTIVES

To report a case of KD initially presenting as a retropharyngeal edema mimicking a deep neck infection, and to review previously published reports in the literature.

CASE REPORT

We report a case of KD in a previously healthy 3-year-old child who presented with acute onset of fever and cervical adenitis, along with computed tomography scan findings of retropharyngeal edema and inflammation. KD was suspected due to persistent fever and no improvement in the patient's condition despite appropriate antibiotic therapy; and other classic findings of KD eventually developed. An echocardiogram obtained on the 10th day of illness revealed pericardial effusion but no coronary ectasia or aneurysm. Treatment with high-dose intravenous immunoglobulin resulted in dramatic clinical improvement. Follow-up echocardiograms obtained 2 and 8 weeks after discharge revealed a small left coronary artery aneurysm (CAA). Nine months later, the CAA had resolved and the patient was well with no sequelae.

CONCLUSIONS

Although unusual, physicians should be aware of retropharyngeal edema as an atypical presentation of KD.

Patterns of Kawasaki syndrome presentation

Kawasaki syndrome (KS) is a systemic disorder of unknown etiology that can lead to coronary artery aneurysm and thrombosis in a significant number of children. It is defined by a number of clinical guidelines set by the Centers for Disease Control (Rauch, A.M., Hurwitz, E.S. (1985) Centers for Disease Control (CDC). Case Definition for Kawasaki syndrome. Pediatr. Infect. Dis. 4, 702-703). Many of the symptoms of this illness may lead the patient to the otolaryngologist. These criteria include injected or fissured lips, injected pharynx, strawberry tongue and cervical lymphadenopathy. When administered in the first 10 days of the illness, gamma globulin has been demonstrated to reduce the prevalence of coronary artery abnormalities (Newburger, J.W., Takahashi, M., Burns, J.C. et al. (1986) Treatment of Kawasaki syndrome with intravenous gamma globulin. N. Engl. J. Med. 315, 341-347). Unfortunately, when a diagnosis of KS is not considered or if a patient presents with unusual symptoms that are not consistent with the CDC guidelines, the diagnosis and treatment of KS can be delayed or even missed. We present a series of patients with KS to illustrate its patterns of presentation.

Tuberculin skin test reactivity in Kawasaki disease

A strongly positive tuberculin skin reaction (> 1.5 cm2) was observed during the acute phase of the illness in 11 children with Kawasaki disease (KD), but not in control pediatric patients with other febrile infections (41 patients) or diseases similar to KD (9 patients). The cutaneous sensitivity to intermediate strength [5 tuberculin units (TU)] purified protein derivative (PPD) inoculation had completely disappeared by the second monthly checkup. Peripheral blood T lymphocytes from KD subjects proliferated vigorously and produced significant amounts of IL-2 in response to the stimulation elicited by 0.05 TU/mL of PPD. In contrast, the proliferative response of, and IL-2 release by, control T cells was within background values. Mounting laboratory evidence suggests that heat shock proteins (HSP) may be involved in the pathogenesis of KD. Our clinical and experimental data may, therefore, have been due to immunologic cross-reactivity between mycobacterial derived HSP65 and its human homologue HPS63 (self P1 antigen). Despite the low number of patients investigated, our findings suggest that the tuberculin skin test and its in vitro correlates (T cell mitogenesis and IL-2 production) could provide simple and reliable diagnostic tools for identifying atypical forms of KD, or vice versa, in subjects not vaccinated against tuberculosis.
