Ramsey hunt syndrome after antimonial treatment for American Cutaneous Leishmaniasis

Abstract Ramsay Hunt Syndrome (RHS), also known as herpes zoster oticus, is caused by the reactivation of varicella zoster virus (VZV) in the geniculate ganglion of the facial nerve. Herein, we report a case of Ramsey Hunt Syndrome in a patient after antimonial treatment for Cutaneous Leishmaniasis. The patient presented with microvesicles grouped on an erythematous base, starting in the neck and ascending towards the scalp margin on the right side of the head. The patient also developed grade V peripheral facial palsy the day after initiating the herpes zoster treatment, this outcome corroborated the assumption of Ramsey Hunt Syndrome.

Síndrome de Ramsay Hunt: revisión narrativa / Ramsay Hunt Syndrome: Narrative Review

El síndrome de Ramsay Hunt (SRH) corresponde a la asociación de la parálisis facial periférica con una erupción vesicular localizada en el pabellón auricular, causada por el compromiso del ganglio geniculado secundario a una infección por el virus de la varicela-zóster (VVZ). Este síndrome es la segunda causa más común de parálisis facial atraumática y representa aproximadamente el 10 %-12 % de las parálisis faciales agudas, con una incidencia anual de 5 por cada 100 000 habitantes en Estados Unidos. El diagnóstico es principalmente clínico y entre las manifestaciones más destacadas se encuentran síntomas neurológicos como otalgia, tinnitus, hipoacusia asociada con parálisis facial junto a lesiones herpéticas características. Dentro de las complicaciones que se pueden presentar en esta entidad se encuentra, principalmente, la neuralgia posherpética, seguida de otras menos frecuentes como la encefalitis, el herpes zóster oftálmico y la mielitis. El manejo actual del SRH se basa en la aplicación de terapias duales con corticosteroides asociados a terapia antiviral, lo cual ha demostrado que el inicio temprano del tratamiento mejora el pronóstico y disminuye la aparición de complicaciones. El pronóstico de esta patología es inferior en comparación a patologías menos severas que comprometen el nervio facial (como la parálisis de Bell) y se ve impactado por varios factores como el inicio oportuno de tratamiento, el grupo etario y la presencia de comorbilidades.

Ramsay Hunt syndrome corresponds to the association of peripheral facial paralysis with a vesicular eruption located in the pinna, caused by the involvement of the geniculate ganglion secondary to infection by the varicella zoster virus. This syndrome is the second causes of atraumatic facial paralysis, representing approximately 10 %-12 % of acute facial paralysis, with an annual incidence of 5 per 100,000 inhabitants. The diagnosis is mainly clinical and among the most prominent manifestations are neurological symptoms such as otalgia, tinnitus, hypoacusis associated with facial paralysis together with characteristic herpetic lesions. Among the complications that may occur in this entity is mainly postherpetic neuralgia, followed by less frequent ones such as encephalitis, ophthalmic herpes zoster and myelitis. Current management of Ramsay Hunt syndrome is based on the application of dual therapies consisting of corticosteroids associated with antiviral therapy, showing that early initiation of treatment improves prognosis and reduces the appearance of complications. The prognosis of this pathology is inferior compared to less severe pathologies that compromise the facial nerve (Bell's palsy) and is impacted by several factors such as the timely initiation of treatment, the age group, and the presence of comorbidities.

Síndrome de Ramsay Hunt. Informe de un caso y revisión de la literatura / Ramsay Hunt syndrome. Case report and literature review

RESUMEN Se presentó paciente masculino de 68 años de edad, con antecedentes de síndrome de Parkinson posinfarto cerebral isquémico antiguo e hipertensión arterial sistémica, con la intensión de describir la experiencia del diagnóstico y tratamiento del síndrome de Ramsay Hunt. El paciente acudió a consulta de Medicina Interna del Policlínico Universitario "Omar Ranedo Pubillones", Guantánamo, por presentar dolor en hemicara izquierda y otalgia homolateral, cefalea y febrícula. Luego, presentó lesiones vesiculosas de aspecto herpético. Se concluyó el diagnóstico definitivo de síndrome de Ramsay Hunt tipo II y se remitió a consulta de Otorrinolaringología, donde se confirmó el diagnóstico. Luego del tratamiento evolucionó satisfactoriamente. Aunque el síndrome de Ramsay Hunt no es un problema de salud, se revela la necesidad de que el médico del nivel primario de atención a la salud se familiarice con las bases teóricas para su diagnóstico y se connota la importancia de la evaluación interdisciplinaria para esta finalidad.

ABSTRACT It was reported a 68 year old male patient with a personal pathological history of post- ischemic stroke Parkinson's syndrome and systemic arterial hypertension and with the intention of describing the experience of diagnosis and treatment of Ramsay Hunt syndrome. Patient presented to his primary health physician at the Univirsity Clinic "Omar Ranedo Pubillones" in Guantanamo, presenting pain in right side of the face and earache, headache and fever. Then, he presented vesicular lesions with a herpetic appearance. It was concluded the definitive diagnosis of Ramsay Hunt syndrome type II and it was referred to Otolaryngology consultation, where the diagnosis was confirmed. After treatment patient's improvement was good. Although Ramsay Hunt syndrome is not a health problem, shows the need for primary care physicians to become familiar with the theoretical basis for its diagnosis and the importance of interdisciplinary evaluation for this purpose.

Ramsay Hunt Syndrome Complicated by Meningoencephalitis and Radiologic findings: a Rare Case Report

Ramsay Hunt syndrome with the complication of encephalitis or meningoencephalitis is rarely reported and uncommon in immunocompetent patients. The radiological manifestations of such cases usually involve the cerebellum and brainstem or exhibit the absence of any abnormality. We report a case of a 78-year-old immunocompetent man hospitalized with Ramsay Hunt syndrome, who later developed meningoencephalitis. The cerebrospinal fluid-study excluded other causes of meningoencephalitis, and the clinical diagnosis indicated varicella zoster virus meningoencephalitis. Magnetic resonance imaging revealed increased signal intensities in the bilateral temporal lobe, midbrain, and pons on T2-weighted imaging, and T2 fluid attenuated inversion recovery and contralateral asymmetric pachymeningeal enhancement. Contrast-enhanced T1-weighted imaging revealed ipsilateral facial nerve enhancement.

Facial Herpes Zoster: A 15-year Retrospective Single-Center Study / 대한피부과학회지

BACKGROUND: Many studies about herpes zoster exist in the Korean dermatologic literature. However, few studies have reported about facial herpes zoster and its complications. OBJECTIVE: The purpose of this study was to investigate the epidemiology, clinical features, and complications of facial herpes zoster. METHODS: We analyzed the medical records of 977 patients who visited Sanggye Paik Hospital between January 2002 and December 2017. We categorized patients into 8 groups based on the dermatomal distribution of herpetic lesions. We investigated the correlations between clinical features, prognosis, and complications. RESULTS: We analyzed the medical records of 977 patients who visited Sanggye Paik Hospital between January 2002 and December 2017. We categorized patients into 8 groups based on the dermatomal distribution of herpetic lesions. We investigated the correlations between clinical features, prognosis, and complications. Results: The most common site of involvement of facial herpes zoster was the ophthalmic branch of the trigeminal nerve (59.2%). Herpes zoster involving the ophthalmic and the maxillary branches of the trigeminal nerves showed a significantly higher incidence rate of herpes zoster ophthalmicus than that observed with herpes zoster involving only the ophthalmic branch (odds ratio 7.373). Age and periorbital swelling were significantly correlated with herpes zoster ophthalmicus (p<0.001). Facial palsy was significantly correlated with otalgia and cutaneous ear involvement (p<0.001). Postherpetic neuralgia (PHN) occurred in 41% of patients with facial herpes zoster. Patients who received antiviral treatment within 3 days showed lower rates of PHN (35.8%) than patients who received treatment after 4 days (45.4%) (p=0.002). CONCLUSION: Facial herpes zoster is associated with several neurological complications. Variables including age, periorbital swelling, otalgia, and cutaneous ear involvement are useful predictors of complications and prognosis. Early institution of antiviral treatment and appropriate interdepartmental consultations are required for better treatment outcomes.

A Case of Recurred Herpes Zoster Oticus Concomitantly Occurred with Zoster Laryngopharyngitis Without Vocal Cord Palsy

Herpes zoster oticus is one of complication of varicella zoster virus (VZV) reactivation in the geniculate ganglion of the facial nerve, which is the most common presentation of herpes zoster in the head and neck region. However, VZV infection of the larynx has rarely been described in the literature compared with Herpes zoster oticus. Moreover, zoster laryngopharyngitis simultaneously occurred with recurred Herpes zoster oticus which has no newly developing motor dysfunction has not been reported yet. Therefore, these diseases are difficult to diagnose due to its rareness. However, distinctive appearances such as unilateral herpetic mucosal eruptions and vesicles are useful and essential in making a quick and accurate diagnosis. Thus, we report a characteristic case of zoster laryngopharyngitis simultaneously occurred with recurred Herpes zoster oticus not accompanied by any newly developing motor palsy.

Ramsay Hunt syndrome

Ramsay Hunt syndrome is a type of acute herpes zoster, which occurs by reactivation of the varicella-zoster virus at the geniculate ganglion. Clinical presentation of Ramsay Hunt syndrome includes a vesicular rash on the ear (herpes zoster oticus) or in the oral mucosa accompanied by acute peripheral facial nerve paralysis. Other cranial nerves such as V, IX, XI, and XII are often involved. Additional variability of the clinical picture of Ramsay Hunt syndrome is produced by varying patterns of skin involvement explained by individual anastomoses between cranial and cervical nerves. Combination treatment containing anti-viral agents and steroids is recommended for the treatment of Ramsay Hunt syndrome. Additionally, early diagnosis of Ramsay Hunt syndrome is a crucial factor to improve damaged nerves in Ramsay Hunt syndrome, which initiates treatment as soon as possible.

Zoster Laryngitis with Multiple Cranial Nerve Palsy Progressed as Ascending Involvement

BACKGROUND: Herpes zoster of the head and neck commonly presents with Ramsay Hunt syndrome. However, vesicular eruptions may occur on the pharyngeal or laryngeal area with multiple lower cranial-nerve (CN) palsy. CASE REPORT: We report on the case of a 54-year-old man with herpes zoster of the pharynx and larynx with multiple CN palsy and persistent hiccups. He initially developed progressive dysphagia, hoarseness, and persistent hiccups (CN IX and X). After admission, Dizziness, hearing impairment, and peripheral facial palsy (CN VII and VIII) were complicated. The results of a polymerase chain reaction test of saliva and vesicular fluid from the ear and throat were strongly positive for varicella zoster virus. The progression of CN palsy was in an ascending sequence. CONCLUSION: We suggest that the sequence of CN palsy may be either ascending or descending, depending on the initial site of involvement.

Clinical Characteristics of Dizziness Associated with Acute Peripheral Facial Palsy

BACKGROUND AND OBJECTIVES: We aimed to assess the clinical significance of dizziness associated with acute peripheral facial palsy (APFP). SUBJECTS AND METHODS: Medical records of patients who visited an otorhinolaryngology clinic at a university hospital and were admitted for treatment of APFP between 2014 and 2016 were thoroughly reviewed. RESULTS: In total, 15.3% (n=15) of patients had dizziness. Continuous, rotatory dizziness without exacerbating factors was most common and frequently accompanied by nausea/vomiting. Dizziness disappeared within 1 week during the hospitalization period. Patients with Ramsay Hunt syndrome (31.0%) had dizziness more frequently than those with Bell’s palsy (8.7%). In addition, higher hearing thresholds and pain around the ear was reported more often in dizzy patients (p < 0.05). Logistic regression analysis revealed that the initial House-Brackmann grade of facial paralysis was solely associated with final recovery, but dizziness was not associated with prognosis. CONCLUSIONS: Patients with APFP may have transient dizziness in the early stage, which may be more frequently accompanied by worse hearing thresholds and/or pain around the ear. However, these symptoms including dizziness seem to be unrelated to final prognosis.

Facial paralysis due to Ramsay Hunt syndrome - A rare condition / Paralisia facial secundária à síndrome de Ramsay Hunt - Uma condição rara

Summary Ramsay Hunt syndrome (or herpes zoster oticus) is a rare complication of herpes zoster in which reactivation of latent varicella zoster virus infection in the geniculate ganglion occurs. Usually, there are auricular vesicles and symptoms and signs such otalgia and peripheral facial paralysis. In addition, rarely, a rash around the mouth can be seen. Immunodeficient patients are more susceptible to this condition. Diagnosis is essentially based on symptoms. We report the case of a diabetic female patient who sought the emergency department with a complaint of this rare entity.

Resumo A síndrome de Ramsay Hunt (ou zóster auricular) é uma complicação rara do herpes-zóster em que ocorre reativação de uma infecção latente pelo vírus varicela-zóster no gânglio geniculado. Geralmente, estão presentes vesículas auriculares e sintomas como otalgia e paralisia facial periférica. Além disso, mais raramente pode haver rash ao redor da boca. Pacientes com imunodeficiência apresentam maior susceptibilidade para essa condição. O diagnóstico é essencialmente pelo quadro clínico. É apresentado o caso de uma paciente diabética que compareceu ao setor de emergência com essa manifestação rara.

Herpes Zoster with Aseptic Meningitis in Immunocompetent Children: A Case Series

Primary clinical features of rash and neurological complications due to varicella zoster virus (VZV) reactivation are rare in a healthy population, especially in immunocompetent children. Early diagnosis and prompt treatment are delayed often due to their rarity. We present four immunocompetent children with VZV reactivation resulting in aseptic meningitis and herpes zoster affecting multiple cranial and spinal nerves. We reviewed the clinical manifestations, laboratory findings, treatment options and outcome of aseptic meningitis associated VZV reactivation. All patients presented with the typical skin lesion of VZV reactivation and definitive laboratory findings of central nervous system infection, without systemic inflammation. Initial manifestations of VZV reactivation included Ramsay Hunt syndrome, herpes zoster ophthalmicus, and herpes zoster affecting the left thoracic dermatomes 4–5. Intravenous acyclovir was administered and all patients recovered fully without any significant sequelae. VZV reactivation can lead to various neurological complications in immunocompetent children. Early recognition and treatment with acyclovir are important for improving the outcome of neurologic complications of VZV reactivation.

Herpes Zoster Oticus without Facial Palsy and Hearing Loss Masquerading as Vestibular Neuritis

Herpes zoster oticus, also called Ramsay-Hunt syndrome, involves the geniculate ganglion and presents with facial nerve palsy, sensorineural hearing loss, vestibular dysfunction, and auricular vesicular lesion. In this case, the patient presented with isolated vestibular dysfunctions without facial palsy and hearing impairment, and these findings were confirmed by electrophysiologic studies including video head impulse testing. Clinicians should be aware of this variation, and differentiate it from vestibular neuritis which usually does not require intensive antiviral therapies.

Cranial Polyneuropathy in Ramsay Hunt Syndrome Manifesting Severe Pharyngeal Dysphagia: a Case Report and Literature Review

Ramsay Hunt syndrome (RHS) is characterized by herpes zoster oticus, facial nerve palsy, and vestibulocochlear symptoms. Dysphagia caused by the involvement of multiple cranial nerves (CNs) in RHS is very rare. We encountered a rare case presented with severe dysphagia due to cranial polyneuropathy involving trigeminal nerve (CN V), facial nerve (CN VII), vestibulocochlear nerve (CN VIII), glossopharyngeal nerve (CN IX), vagus nerve (CN X), and hypoglossal nerve (CN XII) in RHS. This case report suggested that the prognosis for dysphagia in RHS seems favorable, and swallowing rehabilitation therapy could be beneficial in expediting tube removal.

Acute Vestibular Neuritis and Ramsay-Hunt Syndrome / 대한평형의학회지

Acute vestibular neuritis is the disorder characterized by acute, spontaneous vertigo with the unilateral vestibular loss. Reactivation of herpes simplex virus is considered as its cause. Its management consists of symptomatic therapy in the acute phase and following rehabilitation exercise to improve central compensation. The differential diagnosis should include central vestibular disorders mimicking peripheral vertigo. Ramsay-Hunt syndrome, which defined as a herpes zoster oticus with facial paresis, is also a disorder frequently accompanied with vestibular deficit. Combination therapy of acyclovir and corticosteroid is recommended for the treatment. In this review, diagnosis and management of the two disorders are described.

Herpes Zoster in Children and Adolescents: A 10-year Retrospective Study at a Single Institution / 대한피부과학회지

BACKGROUND: Studies on herpes zoster have been extensively reported in Korea. However, few reports have dealt with herpes zoster in children and adolescents. OBJECTIVE: The purpose of this study was to investigate the epidemiological features and clinical characteristics of herpes zoster in children and adolescents. METHODS: During a 10-year period (2005~2014), 95 herpes zoster patients, aged 18 years and younger, were evaluated in regard to the annual, monthly, and seasonal incidences; the age distribution; and the gender ratio. The children and adolescents with herpes zoster were further assessed on the accompanying symptoms, dermatomal distribution, associated diseases, treatments, and complications. RESULTS: Among all the patients with herpes zoster, 2.41% were children and adolescents. The highest incidence was in summer (35.8%). The age group of 10 to 14 years had the highest incidence (40.0%). The male to female ratio was 1.4:1. The common accompanying symptoms were pain (77.9%) and pruritus (22.1%). The most common dermatomal distribution was the thoracic dermatome (50.5%), followed by the cervical (21.1%), the trigeminal (16.8%), the lumbar (7.4%) and the sacral (4.2%) dermatomes. Associated diseases including atopic dermatitis, bronchial asthma, allergic rhinitis, chronic sinusitis, and epilepsy were observed in 23.2%. There was no case with immunosuppression. The most common complication was secondary bacterial infection (5.2%), followed by herpes zoster ophthalmicus or herpes zoster generalisatus (4.2%), Ramsay Hunt syndrome (2.1%), meningitis and recurrent herpes zoster (1.1%). No patient developed postherpetic neuralgia. CONCLUSION: Herpes zoster is rare and relatively mild in healthy immunocompetent children and adolescents. Pruritus was observed in some pediatric patients, but there was no occurrence of postherpetic neuralgia.

Temporal Lobe Retraction Provides Better Surgical Exposure of the Peri-Geniculate Ganglion for Facial Nerve Decompression via Transmastoid Approach

PURPOSE: For the exposure of the labyrinthine segment of the facial nerve, transmastoid approach is not usually considered due to being situated behind the superior semicircular canal. To obtain a better view and bigger field for manipulation in the peri-geniculate area during facial nerve decompression, retraction of temporal lobe after bony removal of tegmen mastoideum was designed via transmastoid approach. MATERIALS AND METHODS: Fifteen patients with traumatic facial paralysis [House-Brackmann (HB) grade IV–VI], 3 patients with Bell's palsy (HB grade V–VI), and 2 patients with herpes zoster oticus (HB grade V–VI) underwent facial nerve decompression surgery between January 2008 and July 2014. In all patients, we performed temporal lobe retraction for facial nerve decompression via the transmastoid approach. Patients were examined using pre operative tests including high-resolution computed tomography, temporal magnetic resonance imaging, audiometry, and electroneurography (degenerative ratio >90%). Facial function was evaluated by HB grading scale before and 6 months after the surgery. RESULTS: After the surgery, facial function recovered to HB grade I in 9 patients and to grade II in 11 patients. No problems due to surgical retraction of the temporal lobe were noted. Compared to the standard transmastoid approach, our method helped achieve a wider surgical view for improved manipulation in the peri-geniculate ganglion in all cases. CONCLUSION: Facial nerve decompression via the transmastoid approach with temporal lobe retraction provides better exposure to the key areas around the geniculate ganglion without complications.
