Varicella-zoster virus reactivation is an important cause of acute peripheral facial paralysis in children

BACKGROUND: Reactivation of herpes simplex virus type 1 is thought to be a major cause of adult idiopathic peripheral facial paralysis or Bell's palsy. However, few studies have examined the pathogenesis of this condition in children. Serologic assays and polymerase chain reaction (PCR) analysis of paired sera and saliva samples were used here to investigate the causes of acute peripheral facial paralysis in pediatric patients. METHODS: A total of 30 children with acute peripheral facial paralysis were recruited. Paired sera were assayed for evidence of herpesvirus, mumps virus or Borrelia infection. PCR was used to detect herpes simplex virus type 1 and varicella-zoster virus (VZV) DNA in saliva samples. RESULTS: Ramsay Hunt syndrome with accompanying zoster lesions was diagnosed clinically in 2 patients, and VZV reactivation was confirmed serologically. VZV reactivation in the absence of zoster (zoster sine herpete) was diagnosed in 9 patients with either serologic assays or PCR. Thus VZV reactivation was demonstrated in 11 of 30 (37%) patients. The prevalence of VZV reactivation among patients between 6 and 15 years of age was significantly higher than in those younger than 5 years of age (53% versus 9%, P = 0.023). CONCLUSIONS: Our data indicate that VZV reactivation is an important cause of acute peripheral facial paralysis in children, especially those between 6 and 15 years of age.     

Acquired peripheral facial palsy in children. Current data illustrated by 66 recent personal cases]

The authors observed 66 cases of peripheral facial palsy (PFP) in children during a 5-year period (1986-1990). Bell's palsy (idiopathic facial paralysis) occurred in 26 children (39.3%), 1 month to 14.5 years old, with a complete recovery in 95% of the cases; a surgical decompression was carried out in 2 cases. The PFP was related to otitis in 16 cases (24.2%): acute otitis media (6), mastitis (4), serous otitis (5), cholesteatoma (1); the treatment was medical and surgical in all cases with complete recovery in 15 cases. In 15 cases the PFP was secondary to trauma (13) or surgery (2); complete spontaneous recovery occurred in 11 cases, and partial recovery following surgical treatment in 2 cases. A viral origin was retained in 6 cases: herpes zoster (3), mumps (1), echovirus (1), herpes (1); the recovery was complete in 4 cases, partial in 2 cases. In 3 cases the PFP was related to a rare cause: lymphoma, metabolic acidosis, Melkerson-Rosenthal syndrome. Bell's palsy remains the main cause of PFP in childhood; other etiologies can be ruled out by the case history, a careful physical examination, and a limited number of laboratory and/or X-ray studies; medical treatment, in particular prednisone, does not seem to have an effect upon the rate of recovery which is spontaneously high; similarly there is no evidence that surgical decompression really modifies the rate of recovery so that the authors suggest that it should be reserved to the complete forms with no clinical and electrical evidence of recovery after 3 weeks.     

Acute Otitis Media and Facial Palsy in Children

ABSTRACT. Two cases of facial palsy in connection with acute otitis media are presented. The patients were 2 months and 2 years old, respectively. In both cases the facial palsy disappeared after treatment with myringotomy and antibiotics. The etiological mechanisms behind and the different approaches to the treatment of facial palsy in children with acute otitis media are discussed.     

Peripheral Facial Palsy in Childhood-Lyme Borreliosis to be Suspected Unless Proven Otherwise

ABSTRACT. 27 consecutive cases with acute peripheral facial palsy were studied for Lyme borreliosis. In 16 out of 27 children Lyme borreliosis could be diagnosed by detection of specific IgM antibodies in CSF. CSF findings allow a clear distinction according to etiology. All children with facial palsy due to Lyme borreliosis revealed lymphocytic CSF pleocytosis, whereas in cases of unknown etiology CSF was usually normal. Bilateral facial palsy occurred only in children with Lyme borreliosis. All cases with a positive history of tick bite and/or erythema migrans in the head-neck region showed ipsilateral neurological affection suggesting a direct invasion via the affected nerve by Borrelia burgdorferi.

Bell's palsy: a guideline proposal following a review of practice

Abstract:   Bell's palsy occurs less frequently in children than in adults. It is important to consider other diagnosis when a child presents with an unilateral rapid onset lower motor neurone Vll nerve paresis. We propose guidelines for the management of Bell's plasy in childhood.     

Chickenpox and the geniculate ganglion: facial nerve palsy,Ramsay Hunt syndrome and acyclovir treatment

Facial nerve palsy has long been considered to have an infectious etiology. Recent diagnostic analyses in children and adults have provided convincing evidence that reactivation of varicella-zoster virus (VZV), sometimes during infectious mononucleosis, can lead to cranial nerve VII palsy. The site of reactivation from latency is the geniculate ganglion. Virus most likely enters the ganglion during chickenpox, via the sensory branches of the facial nerve located on the ear and tongue. Retrospective reviews suggest that patients with VZV-related facial nerve palsy have poorer outcomes than other cases of Bell's palsy. Therefore treatment with acyclovir is suggested when VZV reactivation i slikely.     

Facial paralysis secondary to acute otitis media

We describe a case of facial paralysis in a 19-month-old male recently diagnosed with acute otitis media. Results of his physical examination was remarkable for left-sided peripheral facial nerve palsy with an associated middle ear infection. Physicians should understand the etiology, pathophysiology, treatment options, and prognosis of facial palsy in association with otitis media.     

Facial nerve paralysis secondary to acute otitis media in infants and children

Nowadays, facial paralysis is an uncommon complication of acute inflammation of the middle ear, with an estimated incidence of 0.005%; it was not so rare in the pre-antibiotic era, occurring in 0.5-0.7% of middle ear inflammatory processes. We would like to highlight this complication of acute otitis media, a common paediatric complaint. We present three new cases of facial palsy in children with acute otitis media and discuss the etiological mechanisms and different approaches to the treatment; a flow chart for facial paralysis in acute otitis media is also presented. Our three patients recovered completely after mastoidectomy (first two cases) and myringotomy with antibiotic therapy (third case). Facial paralysis is an uncommon complication of otitis media which requires appropriate care. Following our experience and revision of literature on the subject, antibiotic therapy and myringotomy are the first-line procedures. Surgery should be employed in case of acute or coalescent mastoiditis, suppurative complications and lack of clinical regression.     

Herpes zoster in immunocompetent and immunocompromised Japanese children

BACKGROUND: To confirm epidemiological features of herpes zoster among children with or without immunosuppression, herpes zoster patients who had presented to this hospital were retrospectively investigated. METHODS: Medical records were reviewed for the 92 cases of pediatric herpes zoster patients diagnosed during the period from 1981 to 1998. The age at onset of herpes zoster and of varicella, the interval between varicella and zoster, the dermatomal distribution of herpes zoster and complications were compared between immunocompetent and immunocompromised children. RESULTS: The mean age at onset of zoster in immunocompetent children was 8.5 +/- 4.0 years and in immunosuppressed children was 9.7 +/- 3.8 years. The age at onset of varicella was significantly lower (1.6 +/- 1.8 years) in immunocompetent than in immunosuppressed children (4.6 +/- 2.7 years). The interval between varicella and zoster was 6.2 +/- 3.2 years in immunocompetent children. More than 80% of patients with acute leukemia or malignant lymphoma had herpes zoster within 2 years after diagnosis of malignancy. Lesions of herpes zoster were most frequently found in the thoracic nerve regions. Five of 11 zoster patients with cutaneous dissemination, three of five zoster patients having aseptic meningitis and three of four patients complicated facial palsy were children without underlying disease. CONCLUSIONS: The present study confirmed that varicella in the first year of life was a risk factor in immunocompetent children, as reported previously. Herpes zoster in children without immunosuppression was found not to be as mild as generally accepted.     

Acquired facial palsy with hypertension secondary to Guillain–Barre syndrome

Most cases of facial nerve paresis are idiopathic (Bell's palsy). However, rare and potentially dangerous conditions may present in this manner. We report 2 children presenting with unilateral lower motor neuron facial nerve palsy and hypertension. A diagnosis of Guillain‐Barre syndrome was made in both; literature linking facial nerve palsy in childhood with hypertension and Guillain‐Barre syndrome is reviewed.     

Gradenigo's syndrome with lateral venous sinus thrombosis: successful conservative treatment

Gradenigo's syndrome (GS) is a rare disease characterised by the triad otitis media, pain in the region innervated by the first and the second division of trigeminal nerve and abducens nerve palsy. Septic sinus thrombosis is one of the most frequent and relevant complication of GS; it is often due to persistent damage and late diagnosis. Computed tomography (CT) scan and magnetic resonance imaging (MRI) allow the correct diagnosis in most cases. Surgical therapy may be necessary for a better and more rapid resolution of the disease. We report the case of a 4-year-old child that was admitted for facial nerve palsy and abducens nerve palsy subsequent to a 2-week persistent pain in the right ear. MRI showed infective acute process of the right mastoid and partial ipsilateral sinus thrombophlebitis. The child was treated with high-dose intravenous antibiotics and with oral anticoagulants. A complete resolution of symptoms and radiological alterations were observed within 7 weeks. In conclusion, lateral sinus thrombosis and Gradenigo's syndrome are rare but potential fatal complications of otitis media and mastoiditis. High-dose intravenous antibiotics and a low dose of anticoagulant can achieve a complete recovery without surgery.     

Recurrent facial nerve palsy in paediatric patients

The aim of the study was to investigate the clinical presentation and prognosis of recurrent facial nerve palsy (RFNP) in children. The files of 182 patients referred to the Schneider Children's Medical Centre of Israel for neurological evaluation of isolated peripheral facial nerve palsy between October 1992 and December 1998 were reviewed. RFNP was found in 11 patients (9 females, 2 males), with an incidence of 6%. In two males, the aetiology was traced to Melkersson-Rosenthal syndrome and these patients were separated from the rest of the group. Three children had two episodes of facial nerve paresis which completely resolved clinically within several weeks. Six other children underwent electrophysiological studies. Two of the latter with residual neurological damage, and one child with abnormal blink reflex only, showed decreased facial nerve conduction velocity and abnormal blink reflex. Three children with complete recovery had disturbed blink reflex only with normal nerve conduction. Brain imaging studies as well as laboratory work-up were non-contributory in all cases. CONCLUSION: The frequency of recurrent facial nerve palsy in children was similar to that in adults. The most significant factors in the evaluation of recurrent facial nerve palsy are medical history and physical findings at diagnosis and after short follow-up. In our patients, electrophysiological studies did not have either clinical or prognostic significance. The rate of full clinical recovery is about 70%, lower than in Bell palsy.     

Facial nerve surgery in children

We report results of surgery of the facial nerve in nine cases of CSOM with cholesteatoma in children. Of these cases, seven had facial palsy following mastoid surgery and they needed re-exploration surgery with facial nerve decompression or nerve grafting depending on the extent and degree of trauma to the nerve. The other two cases had facial palsy due to cholesteatoma itself and they were subjected to facial nerve surgery along with mastoid surgery. Results in these nine cases were very encouraging.     

"STRESS" POLYCYTHAEMIA AND PERIPHERAL FACIAL PALSY COMPLICATIONS OF SEVERE HYPERTENSION

Abstract. An 11-month-old boy had an episode of generalized convulsions followed by a right peripheral facial palsy, which resolved gradually within 3 weeks. Three months later he had another similar episode of convulsions followed by a left peripheral facial palsy. On both occasions it was found that he had polycythaemia. A careful physical examination discovered that the child had severe hypertension. Extensive laboratory investigations did not reveal a cause for his hypertension. Haematologic investigations showed that the polycythaemia was due to a contracted plasma volume as a result of the hypertension. The peripheral facial palsy most probably was due to a blood clot in the facial canal, below the origin of the nerve to m. stapedius, as audiograms were normal and lacrimation preserved. Control of the hypertension resulted in resolution of the facial palsy within 4 weeks and normal haematocrit readings within 6 weeks. It should be stressed that every patient with peripheral facial palsy should be examined for hypertension.     

Peripheral facial palsy in childhood--Lyme borreliosis to be suspected unless proven otherwise

27 consecutive cases with acute peripheral facial palsy were studied for Lyme borreliosis. In 16 out of 27 children Lyme borreliosis could be diagnosed by detection of specific IgM antibodies in CSF. CSF findings allow a clear distinction according to etiology. All children with facial palsy due to Lyme borreliosis revealed lymphocytic CSF pleocytosis, whereas in cases of unknown etiology CSF was usually normal. Bilateral facial palsy occurred only in children with Lyme borreliosis. All cases with a positive history of tick bite and/or erythema migrans in the head-neck region showed ipsilateral neurological affection suggesting a direct invasion via the affected nerve by Borrelia burgdorferi.     

Borrelia Infection in Children

ABSTRACT. All children (15 years) admitted during 1986 to Sachs Children's Hospital and presenting signs of facial palsy and/or meningitis, or with a history of known tick bite followed by headache, fatigue and muscle pain, were investigated for antibodies to Borrelia in serum and cerebrospinal fluid. (The hospital's catchment area has a high incidence of tick-borne Borrelia infections.) Significantly elevated antibody titre was found in 15 of the 33 patients, in three cases only in cerebrospinal fluid. Eight of the 15 children had facial palsy, which was concomitant with meningitis in six cases. Intravenous penicillin was given to all 15 patients with positive antibody titre, and additionally to three severely ill small children with facial palsy and meningitis. Furthermore, two cases of erythema chronicum migrans, which is considered pathognomonic for Borrelia infection, were treated with penicillin perorally. Cases of Borrelia infection occurred throughout the year, but with a peak in August. To emphasize the variety of symptoms, three cases are presented in some detail.     

Pseudotumor cerebri with transient Oculomotor palsy

Pseudotumor cerebri is a clinical syndrome characterized by raised intracranial pressure with normal ventricular size, anatomy and position. Headache, vomiting and diplopia are the most common symptoms. Signs include those of raised intracranial pressure including papilledema and absence of focal neurological signs. A secondary cause is identifiable in 50% of children; the most common predisposing conditions are otitis media, viral infection and medications. Management is mainly directed towards identifying and treating the cause and measures to reduce the raised intracranial pressure. Though it is mostly a self limited condition, optic atrophy and blindness can occur. Oculomotor nerve palsy is very rarely associated with pseudotumor cerebri. We report a unique case of pseudotumor cerebri who had left Oculomotor palsy with sparing of the pupillary fibres, which resolved following treatment with oral acetazolamide.     

Lyme borreliosis--the most frequent cause of acute peripheral facial paralysis in childhood

A prospective hospital-based multicentre study in Lower Saxony allowed to investigate the frequency of acute peripheral facial palsy due to Lyme borreliosis and its clinical and laboratory characteristics. Diagnosis of Lyme Borreliosis was based on detection of IgM antibodies against Borrelia burgdorferi in serum and CSF as well, using an IgM capture ELISA. Between June 1986 and October 1987 27 consecutive cases with acute peripheral facial palsy were studied. Lyme borreliosis is the main cause of peripheral facial palsy in childhood. It was verified serologically in two thirds of the cases. All cases with a positive history for a tick bite and/or an erythema migrans in the head-neck region showed ipsilateral neurological affection suggesting a direct invasion via the affected nerve by Borrelia burgdorferi. Peripheral facial palsy due to Lyme borreliosis represents a monosymptomatic meningoradiculitis. All children with Lyme borreliosis revealed a lymphocytic CSF pleocytosis, whereas in cases of unknown etiology CSF findings usually were normal. Therefore, in any case of facial palsy with an inflammatory CSF syndrome Lyme borreliosis has to be suspected unless proven otherwise.     

Randomized, investigator-blinded, multicenter, comparative study of gatifloxacin versus amoxicillin/clavulanate in recurrent otitis media and acute otitis media treatment failure in children

BACKGROUND: Recurrent otitis media and acute otitis media treatment failure are commonly encountered in the pediatric population. OBJECTIVE: To compare the clinical efficacy of gatifloxacin with amoxicillin/clavulanate for the treatment of acute otitis media treatment failure and recurrent otitis media. METHODS: Three hundred fifty-four children 6 months-7 years with recurrent otitis media and/or acute otitis media failure were stratified according to age (younger than 2 years versus 2 years or older) and then randomly assigned to 10 days of treatment with gatifloxacin 10 mg/kg once daily or amoxicillin/clavulanate 90 mg/6.4 mg in 2 divided doses. Tympanocentesis was performed in 116 children with acute otitis media treatment failure and 52 with recurrent otitis media at study entry to validate the clinical diagnosis and provide microbiologic data. The primary outcome measure was clinical resolution of infection at the test-of-cure visit 3-10 days after completing treatment. RESULTS: Clinical resolution of acute otitis media was observed in 79.0% (49 of 62) of clinically evaluable children younger than 2 years and 90.3% (56 of 62) of those 2 years or older who were treated with gatifloxacin as compared with 77.6% (45 of 58) of children younger than 2 years and 79.7% (47 of 59) of children 2 years or older treated with amoxicillin/clavulanate. In patients with acute otitis media treatment failure, clinical response rates for children younger than 2 years and those 2 years or older were 87.5% (21 of 24) and 97.0% (32 of 33) with gatifloxacin versus 63.6% (14 of 22) and 83.9% (26 of 31) with amoxicillin/clavulanate. The corresponding clinical response rates in patients with recurrent otitis media were 79.2% (19 of 24) and 85.7% (18 of 21) with gatifloxacin and 90.5% (19 of 21) and 76.0% (19 of 25) with amoxicillin/clavulanate. Clinical success in those subjects having pretreatment middle ear fluid pathogens was similar for the 2 regimens [80.0% (24 of 30) gatifloxacin, 77.1% (27 of 35) amoxicillin/clavulanate]. Emergence of fluoroquinolone-resistant strains was not observed. Both drugs were generally well-tolerated. Diarrhea was the most common drug-related adverse event (10% gatifloxacin, 18% amoxicillin/clavulanate). No evidence of abnormal joint or gait findings was found during a 12-month follow-up. CONCLUSIONS: Gatifloxacin once daily is at least as effective and well-tolerated as amoxicillin/clavulanate twice daily in children with acute otitis media treatment failure or recurrent otitis media. There was no evidence of arthrotoxicity or emergence of fluoroquinolone-resistant bacteria in gatifloxacin-treated children.
