Persistent idiopathic facial pain, a diagnosis and treatment of challenge. Case report

ABSTRACT BACKGROUND AND OBJECTIVES: Persistent idiopathic facial pain is a chronic disease with neuropathic origin, whose etiology is usually unknown; it is a medical condition that does not respond satisfactorily to drug therapy. It is also a disease with a major impact on patient quality of life and difficult to diagnose. This study aimed to report the diagnosis of a complex, persistent idiopathic facial pain, the pharmacological intervention taken and the adoption of integrative and complementary practices for the management of persistent idiopathic facial, as well as the clinical course and the impact of these actions on the patient's quality of life. CASE REPORT: A female patient, 52, diagnosed 06 years ago as a carrier of persistente idiopathic facial pain associated with bruxism and temporomandibular disorders. The patient presented with a complaint of orofacial pain which did not meet the diagnostic criteria for temporomandibular disorders. The patient also presented myofascial and trigeminal neuralgia pain in the left buccal region which emerged after performing a root canal procedure. The therapeutic plan adopted was based on pharmacological therapy with pregabalin (450mg) in combination with venlafaxine hydrochloride (150mg), continuously. As additional measures, weekly acupuncture sessions, therapy sessions with psychologists, including hypnosis and meditation, as well as peripheral nerve and a venous block during crises and botulinum toxin application were applied. CONCLUSION: The therapeutic plan adopted led to a considerable improvement in the patient's quality of life, evidenced by the reduction in pain intensity and a decrease in the frequency of painful crises. The need for interdisciplinary monitoring, as it is a multifactorial disease, as well as for the ongoing training of various categories of health professionals involved in the treatment of persistent idiopathic facial, given that it is a complication which is rare and difficult to diagnose, is observed.

RESUMO Justificativa e objetivos: A dor facial idiopática persistente é uma doença crônica de origem neuropática cuja etiologia é normalmente desconhecida. É uma condição médica que não responde satisfatoriamente à farmacoterapia. Também é uma doença com grande impacto na qualidade de vida do paciente, e difícil de diagnosticar. O objetivo deste estudo foi reportar o diagnóstico de dor facial idiopática persistente, complexa, a intervenção farmacológica usada e a adoção de práticas integrativas e complementares para o manuseio da dor facial idiopática persistente, além do curso clínico e o impacto dessas ações na qualidade de vida do paciente. RELATO DO CASO: Paciente do sexo feminino, 52 anos, diagnosticada há 6 anos como portadora de dor facial idiopática persistente associada a bruxismo e distúrbio temporomandibular. A paciente apresentou-se com queixa de dor orofacial que não atendeu os critérios diagnósticos de distúrbio temporomandibular. A paciente também apresentou dor miofascial e neuralgia do trigêmeo na região esquerda da boca que surgiram depois de um procedimento de tratamento de canal. O plano terapêutico adotado foi pregabalina (450mg) em combinação com cloridrato de venlafaxina (150mg), contínuo. Como medidas adicionais, sessões semanais de acupuntura, terapia com psicólogo, incluindo hipnose e meditação, além de bloqueio do nervo periférico e bloqueio venoso durante as crises e aplicação de toxina botulínica. CONCLUSÃO: O plano terapêutico adotado trouxe melhora considerável na qualidade de vida da paciente, evidenciada pela redução da intensidade da dor e pela diminuição na frequência das crises dolorosas. Há necessidade de monitoramento interdisciplinar, por ser uma doença multifatorial, e de capacitação constante nas diversas categorias de profissionais de saúde envolvidos no tratamento da dor facial idiopática persistente, vista ser uma complicação rara e difícil de diagnosticar.

Personality, coping and atypical facial pain. Case reports / Personalidade, enfrentamento e dor facial atípica. Relato de casos

ABSTRACT BACKGROUND AND OBJECTIVES: Idiopathic facial pain is a chronic condition with unknown etiology and pathophysiology. Its diagnostic criteria depend on the exclusion of any somatic cause of orofacial pain. Several studies have investigated anxiety and depression, but there is a lack of publications about personality. The objective of this study was to describe three cases of patients with idiopathic facial pain that had their temperament and character evaluated in order to verify the relation between the findings with pain behavior and pain characteristics. The instruments used were a free interview and the Temperament and Character Inventory. CASE REPORTS: Case 1 was proactive and had high scores of cooperativity and self-transcendence correspondent to the well-coping behavior. On the other side, cases 2 and 3 showed similarities about their harm avoidance, novelty seeking and poor coping, correspondent to a self-protective insecure personality. CONCLUSION: These cases show the importance of personality assessment in order to determine coping strategies in complex chronic facial pain such as idiopathic facial pain.

RESUMO JUSTIFICATIVA E OBJETIVOS: Dor facial idiopática persistente é uma condição crônica cujas etiologia e fisiopatologia permanecem obscuras. Os critérios diagnósticos dependem da exclusão de todas as possíveis causas somáticas de dor orofacial. Vários estudos investigaram frequentes comorbidades psiquiátricas como ansiedade e depressão, mas há carência de estudos que tenham observado aspectos de personalidade nesses doentes. O objetivo deste estudo foi descrever três casos de pacientes com dor facial idiopática persistente que foram avaliados quanto a traços de personalidade e de caráter, bem como a associação desses traços com as características da dor e o comportamento doloroso. Os instrumentos utilizados foram a entrevista livre e o Inventário de Caráter e Temperamento de Cloninger. RELATO DOS CASOS: O caso 1 apresentava traços de proatividade e altos índices de cooperatividade e autotranscendência, correspondentes com seu perfil de bom enfrentamento. Por outro lado, os casos 2 e 3 apresentaram similaridades quanto à evitação de dor, busca por novidades e enfrentamento pobre, o que correspondeu a uma personalidade insegura e autoprotetora. CONCLUSÃO: Esses casos mostram a importância de abordar a personalidade do paciente para que estratégias de enfrentamento adequadas sejam estabelecidas para a dor facial crônica complexa.

The effect of stellate ganglion block on the atypical facial pain

Atypical facial pain (AFP) is a type of facial pain which does not fulfill any other diagnosis. It has several features such as no objective signs, no obvious explanation of the cause and poor response to treatments. We report a case of a female patient with AFP on the left maxillary area. The pain was increased by cold innocuous stimulation and thermography showed that the temperature on the painful area was significantly decreased. The pain was successfully alleviated by stellate ganglion block (SGB). Therefore, SGB can be effectively used to treat AFP.

Parálisis de Bell y dolor facial asociados con infección por Toxocara sp / Bell's palsy and facial pain associated with toxocara infection

Objectives: Toxocarosis involving cranial nerves is extremely rare and almost exclusively concerns the optic nerve. Toxocarosis involving the seventh cranial nerve has not been reported. Case report: A 33y male developed left-sided Bell's palsy two days after left-sided otalgia 6y before. Despite extensive diagnostic work-up at that time the cause of Bell's palsy remained unknown. During the following years Bell's palsy slightly improved but retromandibular pain remained almost unchanged and he developed enlarged lymph nodes along the jugular veins, submandibularly, and in the trigonum caroticum. Re-evaluation 6y later revealed an increased titer of serum antibodies against Toxocara canis and a positive Westernblot for Toxocara canis ES-antigen. Despite absent eosinophilia in the serum, toxocarosis was diagnosed and a therapy with albendazole initiated, with benefit for retromandibular pain, but hardly for Bell's palsy or enlarged lymph nodes. CSF investigations after albendazole revealed a positive Westernblot for antibodies against toxocara but absent pleocytosis or eosinophilia, and negative PCR for Toxocara canis. Conclusions: Visceral larva migrans due to Toxocara canis may be associated with Bell's palsy, retromandibular pain, and lymphadenopathy. A causal relation between Bell's palsy and the helminthosis remains speculative. Adequate therapy years after onset of the infestation may be of limited benefit.

Objetivos: La toxocarosis que compromete los nervios craneales es extremadamente infrecuente y afecta casi exclusivamente al nervio óptico. No ha sido comunicada la toxocarosis que afecte al séptimo nervio cranial por lo que se expone un caso clínico. Caso clínico: Varón de 33 años que había presentado seis años antes, una otalgia izquierda seguida dos días más tarde de una parálisis de Bell ipsilateral. A pesar de un exhaustivo estudio, la causa de esta parálisis quedó sin etiología. En los años siguientes la parálisis mejoró moderadamente pero persistió un dolor retromandibular casi sin variaciones y el paciente desarrolló adenopatías en la cadena yugular, submandi-bulares y en el triángulo carotídeo. Una re-evaluación efectuada seis años más tarde detectó un título elevado de anticuerpos contra Toxocara canis y un antígeno ES de T. canis positivo mediante Westernblot. A pesar de no haber eosinofilia en la sangre, se diagnosticó una toxoca-rosis iniciándose terapia con albendazol, con lo cual se observó una reducción del dolor retro-mandibular aunque escaso beneficio sobre la parálisis de Bell y los ganglios comprometidos. El líquido cefalorraquídeo analizado después de haberse efectuado la cura con albendazol reveló un test de Westernblot positivo para anticuerpos anti-toxocara, en ausencia de pleocitosis o eosinofilia, y una RPC para Toxocara canis negativa. Conclusiones: El síndrome de larva migrans visceral debido a T. canis puede asociarse con parálisis de Bell, dolor retroman-dibular y linfoadenopatías. La relación causal entre la parálisis de Bell y la helmintosis permanece en el plano especulativo. La terapia anti-parasitaria realizada años tras la instalación de una infestación puede tener un beneficio aunque limitado.

Refractory craniofacial pain: is there a role of periodontal disease as a comorbidity? / Dor refratária crânio-facial: há algum papel para a doença periodontal como morbidade associada?

OBJETIVE: To evaluate the influence of the periodontal disease (PD), a chronic infection, in patients with chronic craniofacial pain complaints. METHOD: Twenty patients with chronic craniofacial pain and PD (CFP group) and 20 patients with PD (PD group) were assessed before and after periodontal treatment (baseline, 30 and 180 days after treatment). The paramenters evaluated were: plaque index, bleeding index, clinical probe insertion, Visual Analogic Scale (VAS) for pain intensity and Numerical Rating Scale (NRS) and Verbal Rating Scale (VRS) for the "chief complaint". RESULTS: After 180 days PD was controlled in both groups (p<0.001); the VAS decreased in CFP group (p<0.001); "chief complaint" improved (p=0.005 and p=0.027, respectively in CFP and PD group). VRS showed improvement between the groups in 30 (p=0.004) and 180 days (p=0.001). CONCLUSION: These results suggest a possible influence of periodontal disease, as a comorbidity, in refractory craniofacial pain patients and in their pain levels.

OBJETIVO: Avaliar a influência da doença periodontal (DP) em pacientes com queixas de dores crônicas crânio-faciais. MÉTODO: Vinte pacientes com dor crônica crânio-facial e DP (CFP group) e 20 pacientes com DP (PD group) foram avaliados antes e depois do tratamento periodontal (baseline, 30 e 180 dias). Avaliações: índice de placa, índice de sangramento gingival, inserção clínica de bolsa, Escala Visual Analógica (VAS) para a dor, Escalas Numérica (NRS) e Verbal (VRS) para as "queixas principais". RESULTADOS: Após 180 dias a DP foi controlada em ambos os grupos (p<0,001); a VAS reduziu no CFP group (p<0,001); a "queixa principal" melhorou (p=0,005 e p=0,027, respectivamente nos grupos CFP e PD). A VRS mostrou diferença entre os grupos em 30 (p=0,004) e 180 dias (p=0,001). CONCLUSÕES: Estes resultados sugerem a provável influência da doença periodontal, como morbidade associada, nos níveis de dor de pacientes com dores crônicas crânio-faciais.

Burning mouth complaints: clinical characteristics of a Brazilian sample

OBJECTIVE: Evaluation of the clinical characteristics of burning mouth complaints (BMC) in a series of Brazilian patients referred to a large teaching hospital. MATERIALS AND METHODS: 66 patients with burning mouth complaints were evaluated through a standardized protocol. RESULTS: 56 women and 10 men were examined, ranging in age from 35-83 years. The primary location of the complaints was reported to be the tongue. Thirty-six patients reported a precipitating event. The mean VAS pain levels were 7.5 in women and 6.11 in men. The average estradiol levels in women were low (<13 pg/ml); 80 percent of all patients reported a concomitant chronic disease, 55 percent of all patients wore total dentures, 54 percent of all patients reported subjective xerostomia, 48 percent of all patients reported sleep disturbances and 66 percent reported phantom taste. No statistical differences were found between groups with or without a precipitating event in VAS: (p=0.139), in the Number of Words Chosen (NWC) (p=0.259) and Pain Rating Index (PRI) (p=0.276) sections of the McGill Pain Questionnaire (MPQ). CONCLUSION: The existence of systemic comorbidities, self-reported sleep disturbances and taste alterations indicates possible correlations and the need for a careful systemic evaluation of each patient; there were no differences between patients with and without precipitating events.

OBJETIVO: Avaliar as características clínicas de pacientes brasileiros com queixas de ardência buccal atendidos em um hospital escola. MÉTODO: 66 pacientes com queixas de ardência bucal foram avaliados através de exame padronizado para esse tipo de queixa. RESULTADOS: 56 mulheres e 10 homens foram examinados consecutivamente. As idades variaram de 35-83 anos. A localização das queixas foi principalmente na língua e 36 pacientes relataram algum evento precipitante. A Escala Visual Analógica (EVA) a intensidade da ardência (dor) foi: mulheres 7.5 (média) e homens 6.11 (média). Os níveis de estradiol foram baixos (<13 pg/ml); 80 por cento dos pacientes relataram doença crônica associada, 55 por cento usavam dentadura; 54 por cento relataram xerostomia subjetiva; 48 por cento distúrbios subjetivos do sono e 66 por cento gosto fantasma. Não houve diferença da intensidade da EVA (p=0.139) ou dor pelo questionário McGill NWC (p=0.259) and PRI (p=0.276), entre os grupos com e sem eventos precipitantes. CONCLUSÕES: A existência de doenças crônicas associadas, o auto-relato de distúrbios do sono e as alterações de paladar indicam necessidade de avaliação sistêmica cuidadosa nesses pacientes; não houve diferenças entre os grupos com e sem evento precipitante.

A Comparison of Personality Characteristics in Trigeminal Neuralgia and Atypical Facial Pain Using Minnesota Multiphasic Personality Inventory (MMPI) / 대한마취과학회지

BACKGROUND: Trigeminal neuralgia and atypical facial pain are representative disease entities of chronic facial pain. Most patients of these disaeses could be accompanied with psychological, emotional problems as their pain become chronic. The purpose of this study is to investigate whether different types of chronic facial pain lead to alteration in personality disorder or they are associated with particular characteristics of personality disorders using Minnesota multiphasic personality inventory (MMPI). METHODS: 40 patients of trigeminal neuralgia and 21 patients of atypical facial pain who had responded MMPI were enrolled in this study. Two groups were compared for age, sex, pain intensity (Visual analogue scale, VAS), duration of pain, MMPI scores and psychological impression from MMPI results. RESULTS: Pain intensity and chronicity were more severe and longer in trigeminal neuralgia group than atypical facial pain. However, some MMPI profiles such as hypochondriasis and hysteria were significantly elevated in atypical facial pain. Pain intensity and duration did not correlate with MMPI profiles in each group. Meaningful psychological impression from MMPI results which were interpreted by one psychologist were shown in 13 patients of trigeminal neuralgia (32.5%) and 14 patients of atypical facial pain (66.7%). Especially, psychosomatic disorder was most frequently found in atypical facial pain patients (47.6%). CONCLUSIONS: Atypical facial pain have more psychologic and emotional problems than trigeminal neuralgia, regardless of pain intensity and chronicity. Therefore, psychologic evaluation and treatment should be considered in atypical facial pain.

A Case of Atypical Facial Pain Treated with Toki-shigyaku-ka-goshuyu-shokyo-to / 日本東洋医学雑誌

A case of atypical facial pain treated with Toki-shigyaku-ka-goshuyu-shokyo-to was reported. The patient was a 30-year-old female with oversensitivity to cold. She had suffered from intractable atypical facial pain in her left cheek for eight years. Diagnostic images showed no organic lesion and microvascular compression along the left trigeminal nerve. Although conventional medical therapy had not been successful in relieving the pain, Toki-shigyaku-ka-goshuyu-shokyo-to, in combination with several analgetic agents, was therapeutically effective. Later, Toki-shigyaku-ka-goshuyu-shokyo-to alone was effective in relieving painful episode.
