Chronic pain and vitamin B12 deficiency, a challenging and important differential diagnosis. Case report / Dor crônica e deficiência de vitamina B12, um diagnóstico diferencial desafiador e importante. Relato de caso

ABSTRACT BACKGROUND AND OBJECTIVES: The study's objective was to present a case of diffuse chronic pain with 36 months of development, associated with recurrent oral aphthous ulcers and glossitis, highlighting the importance of the wide differential diagnosis and the possibility of vitamin B12 deficiency as a cause. CASE REPORT: Male patient, 39 years-old, white, reported diffuse pain predominantly in the cervical, thoracic, abdominal, thighs and left knee regions, besides the presence of frequent oral aphtae, lasting more than 5 days, multiple and painful, predominantly on the tongue, for 6 months. The condition was attributed to Behçet's disease, but there was complete and permanent remission after treatment with vitamin B12. CONCLUSION: It's important to insert vitamin B12 deficiency for differential diagnosis in chronic pain scenarios.

RESUMO JUSTIFICATIVA E OBJETIVOS: O objetivo deste estudo foi apresentar um caso de dor crônica difusa com 36 meses de evolução, associada com aftas orais de repetição e glossite, destacando a importância do amplo diagnóstico diferencial e da possibilidade da deficiência de vitamina B12 como causa. RELATO DO CASO: Paciente do sexo masculino, 39 anos, branco, referindo dores difusas que predominavam em região cervical, torácica, abdominal, coxas e joelho esquerdo, além da presença de aftas orais frequentes, com duração superior a 5 dias, múltiplas e dolorosas, predominando na língua, há 6 meses. O quadro foi atribuído à doença de Behçet, mas houve remissão total e permanente após tratamento com vitamina B12. CONCLUSÃO: É importante inserir a deficiência de vitamina B12 para o diagnóstico diferencial em quadros de dor crônica.

Prevalence and heritability of psoriasis and benign migratory glossitis in one Brazilian population

Abstract: Background: An oral condition associated to psoriasis is benign migratory glossitis. The review of the literature does not show any publication about heritability in both soriasis and benign migratory glossitis and prevalence of psoriasis in the Brazilian population. Objective: This research was carried out in order to determine the prevalence of psoriasis and benign migratory glossitis in the Brazilian population from a Brazilian sample, as well as the heritability in these conditions. Methods: Six thousand patients were studied from the records of the outpatient dermatology department. The sample had 129 patients with cutaneous psoriasis, 399 with benign migratory glossitis without psoriasis and a control group with 5,472 patients. After data collection, the statistical analysis was made using Woolf, Chi-square and Falconer tests. Results: The prevalence of psoriasis was 2.15% and the benign migratory glossitis was 7.0%. The prevalence of benign migratory glossitis in the psoriasis group was high (16.3%), and that was statistically significant. Family history in the psoriasis group was 38% for the condition itself and 2,75% for benign migratory glossitis and in the benign migratory glossitis group was 17.54% for the condition itself and 1.5% for psoriasis. The study of heritability was 38.8% for psoriasis and 36.6% for benign migratory glossitis, both with medium heritability. Study limitations: This study was only in the state of São Paulo. Conclusion: This is the first publication that quantifies how much of these conditions have a genetic background and how important the environmental factors are in triggering them.

Papillary atrophy of the tongue and nutritional status of hospitalized alcoholics / Glossite atrófica e estado nutricional de alcoolistas hospitalizados

BACKGROUND: Atrophy of the papillae, mucosa, and dorsum of the tongue are considered classical signs of nutritional deficiencies. OBJECTIVE: To assess the nutritional status of hospitalized alcoholics with or without papillary atrophy of the tongue. METHODS: This study was performed with 21 hospitalized alcoholics divided into Atrophic Glossitis Group (n=13) and Normal Tongue Group (n=8). Healthy, non-alcoholic volunteers composed the Control Group (n=8). Anthropometry and bioelectric impedance were performed, and serum vitamins A, E, and B12 were determined. RESULTS: There were no statistical differences in relation to age (46.7±8.7 vs. 46.8±15.8 years) or gender (92.3% vs. 87.5% male), respectively. Control Group volunteers were also paired in relation to age (47.5±3.1 years) and male predominance (62.5%). In relation to hospitalized alcoholics without atrophic lesions of the tongue and Control Group, patients with papillary atrophy showed lower BMI (18.6 ± 2,5 vs 23.8 ± 3.5 vs 26.7 ± 3,6 kg/m² ) and body fat content 7.6 ± 3.5 vs 13.3 ± 6.5 vs 19.5 ± 4,9 kg). When compared with the Control Group, alcoholic patients with or without papillary atrophy of the tongue showed lower values of red blood cells (10.8 ± 2.2 vs 11.8 ± 2.2 vs 14.5 ± 1,6g/dL) and albumin (3.6 ± 0.9 vs 3.6 ± 0.8 vs 4.4 ± 0.2g/dL). The seric levels of vitamins A, E, and B12 were similar amongst the groups. CONCLUSION: Hospitalized alcoholics with papillary atrophy of the tongue had lower BMI and fat body stores than controls, without associated hypovitaminosis.

FUNDAMENTOS: A deficiência crônica de nutrientes pode levar à hipotrofia das papilas e da mucosa e do dorso da língua, considerada um sinal clássico de subnutrição protéico-energética. OBJETIVO: O objetivo do presente estudo é comparar o estado nutricional, incluindo as dosagens dos níveis séricos de vitaminas A, E e B12 em pacientes alcoolistas com ou sem alterações tróficas das papilas linguais. MÉTODOS: O estudo caso-controle incluiu 21 pacientes adultos alcoolistas internados em um hospital universitário. Utilizando-se de um sistema de fotografia da cavidade oral, dois clínicos independentes classificaram os indivíduos alcoolistas de acordo com a presença ou não de alterações tróficas na língua. Foram registrados os dados antropométricos, a composição corporal pela impedância bioelétrica e os exames laboratoriais para avaliação clínica e nutricional, incluindo dosagens das vitaminas A, E e B12. O estudo incluiu ainda voluntários saudáveis, não alcoolistas como Grupo Controle (n=8). A comparação entre os grupos foi feita por ANOYA-F ou pelo teste de Kruskal-Wallis, de acordo com a curva de normalidade dos resultados. Foram considerados significativos diferenças com p < 0,05. RESULTADOS: De acordo com a presença de alterações tróficas nas papilas linguais, os pacientes alcoolistas foram alocados no Grupo Língua Despapilada (n=13) e Grupo Língua Normal (n=8), sem diferença estatística quanto à idade (46,7 ± 8,7 vs 46,8 ± 15,8 anos) e gênero masculino (92,3 vs 87,5%). Os voluntários do Grupo Controle apresentaram 47,5 ±3,1 anos, sendo 62,5% do gênero masculino. Os pacientes alcoolistas com hipotrofia papilar apresentaram menor IMC (18,6 ± 2,5 vs 23,8 ± 3,5 vs 26,7 ± 3,6 kg/m2) e gordura corporal (7,6 ± 3,5 vs 13,3 ± 6,5 vs 19,5 ± 4,9 kg), quando comparados com os demais grupos. Em relação ao Grupo Controle, os alcoolistas apresentaram menores valores de hemoglobina (10,8 ± 2,2 vs 11,8 ± 2,2 vs 14,5 ± 1,6 g/dL) e albumina sérica (3,6 ± 0,9 vs 3,6 ± 0,8 vs 4,4 ± 0,2 g/dL). Os níveis plasmáticos de vitaminas A, E e B12 foram similares entres os grupos. CONCLUSÃO: Os pacientes alcoolistas com achados físicos de hipotrofia de papilas linguais apresentam menores valores em medidas antropométricas, de hemoglobina e albumina séricas que os grupos Controle ou de alcoolistas sem língua despapilada. Não houve evidências de hipovitaminoses associadas.
