Exogenous intoxication by non-prescribed use of vitamin D, a case report.

BACKGROUND: This case report, unlike the current literature related to vitamin D intoxication, aims to highlight the risk of self-medication, and how publicity boosts the acquisition of vitamins for different purposes, increasing consumption with no professional indication or supervision. This practice can pose a serious health risk to the population. CASE PRESENTATION: Our patient, a brazilian retired 64-year-old female, presented to the emergency service with post-prandial food vomiting of undigested content and stabbing abdominal pain with worsening during palpation. Concomitantly, onset of sporadic frontal headache, fatigue, hyporexia, weight loss of 18 kg in the same period, severe pruritus, musculoskeletal pain in the limbs and nocturia. The physical examination showed hypertension (160/80 mmHg) and itchy macules in the lower limb. Initially, the main diagnostic hypotheses were multiple myeloma, hyperparathyroidism and pancreatitis secondary to hypercalcemia, osteolytic neoplasms and other neoplasms that present with hypercalcemia. However, blood count, parathyroid hormone, chest X-ray, immunoglobulins, myelogram and bone marrow biopsy were not compatible with these diagnoses. Meanwhile, 25 OH vitamin D dosage and diluted vitamin D test confirmed the diagnosis of hypervitaminosis D. Hypercalcemic crisis was managed with vigorous hydration (50 ml/kg in 2 h), furosemide, bisphosphonates and blood pressure control with amlodipine and atenolol. Subsequently, the patient was discharged from the outpatient clinic with complete remission of symptoms, weight gain, serum calcium values of 10.76 mg/dL and ionizable calcium values of 6.52 mg/dL. CONCLUSION: Our report summarizes the possible consequences of using a vitamin compound without supervision of a competent professional, as these substances are mistakenly considered non-toxic. To add, little information is available about the supplements' metabolism and their biological effects. Therefore, It is difficult to diagnose intoxication. This case report shows that even the self-administration of a product designed to bring health benefits can become a risky behavior. These vitamin and mineral supplements are supposed to bring patient empowerment and reduce government spending in health-care, but indeed represent a significant public health concern due to possible overdose and drug interactions.

Esophageal manometry in systemic sclerosis: findings and association with clinical manifestations.

INTRODUCTION: Systemic sclerosis (SSC) is an autoimmune disorder that affects several organs of unknown etiology, characterized by vascular damage and fibrosis of the skin and organs. Among the organs involved are the esophagus and the lung. OBJECTIVES: To relate the profile of changes in esophageal electromanometry (EM), the profile of skin involvement, interstitial pneumopathy (ILD), and esophageal symptoms in SSC patients. METHODS: This is an observational, cross-sectional study carried out at the SSC outpatient clinic of the Hospital de Clínicas of the Federal University of Uberlândia. After approval by the Ethics Committee and signed the terms of consent, 50 patients were initially enrolled, from 04/12/2014 to 06/25/2015. They were submitted to the usual investigations according to the clinical picture. The statistical analysis was descriptive in percentage, means, and standard deviation. The Chi-square test was used to evaluate the relationship between EM, high-resolution tomography, and esophageal symptoms. RESULTS: 91.9% of the patients had some manometric alterations. 37.8% had involvement of the esophageal body and lower esophageal sphincter. 37.8% had ILD. 24.3% presented the diffuse form of SSC. No association was found between manometric changes and clinical manifestations (cutaneous, pulmonary, and gastrointestinal symptoms). CONCLUSION: The present study confirms that esophageal motility alterations detected by EM are frequent in SSC patients, but may not be related to cutaneous extension involvement, the presence of ILD, or the gastrointestinal complaints of patients.

RESUMO INTRODUÇÃO A esclerose sistêmica (ES) é uma doença autoimune que afeta vários órgãos de etiologia desconhecida, caracterizada por dano vascular e fibrose da pele e órgãos. Entre os órgãos envolvidos estão o esôfago e o pulmão. OBJETIVOS Relacionar o perfil das alterações na eletromanometria (ME), o perfil de acometimento da pele, a pneumopatia intersticial (PI) e os sintomas esofágicos em pacientes com ES. MÉTODO Trata-se de um estudo observacional, transversal, realizado no ambulatório de SSC do Hospital das Clínicas da Universidade Federal de Uberlândia. Após aprovação pelo Comitê de Ética e assinatura dos termos de consentimento, 50 pacientes foram inicialmente convidados, de 04/12/2014 a 25/06/2015. Eles foram submetidos às investigações usuais de acordo com o quadro clínico. A análise estatística foi descritiva em porcentagem, média e desvio padrão. O teste Qui-quadrado foi utilizado para avaliar a relação entre ME, tomografia de alta resolução e sintomas esofágicos. RESULTADOS 91,9% dos pacientes apresentaram alterações manométricas. 37,8% tinham envolvimento do corpo esofágico e do esfíncter esofágico inferior. 37,8% tinham IP. 24,3% apresentaram a forma difusa da ES. Não há associação entre alterações manométricas e manifestações clínicas (sintomas cutâneos, pulmonares e gastrointestinais). CONCLUSÃO O presente estudo confirma que as alterações da motilidade esofágica detectadas pela EM são frequentes em pacientes com SSC, mas podem não estar relacionadas ao envolvimento cutâneo, à de DPI ou às queixas gastrointestinais dos pacientes.

Prevalence of psoriatic arthritis in a large cohort of Brazilian patients with psoriasis.

OBJECTIVE: To determine the prevalence of psoriatic arthritis (PsA) in a large cohort of Brazilian patients with psoriasis (PsO) being seen at dermatology centers. METHODS: A multicenter study was conducted in 4 university dermatology clinics. In each center, consecutive patients with confirmed diagnoses of PsO were evaluated by a rheumatologist. Individuals were classified as having PsA according to the ClASsification criteria for Psoriatic ARthritis (CASPAR). Laboratory tests and radiographs were performed, as needed, based on the clinical judgment of the rheumatologist. RESULTS: A total of 524 patients with PsO were evaluated. The mean age was 48.5 ± 14.5 years, 50% were women, and the mean PsO duration was 15.4 ± 11.7 years. A diagnosis of PsA was documented in 175 patients (33%), of whom 49% were newly identified by the rheumatologist. Most individuals with PsA (72%) had peripheral involvement, 11% had isolated axial involvement, and 17% had both peripheral and axial involvement. Dactylitis occurred in 20% and clinical enthesitis in 30% of the patients. Laboratory and/or radiograph tests were necessary for a definitive diagnosis of PsA in 42 of 175 individuals (24%). CONCLUSION: In our study, one-third of Brazilian patients with PsO, followed in dermatology settings, were diagnosed with PsA by a rheumatologist. Almost half of subjects with PsA had no previous diagnosis. A collaboration between dermatologists and rheumatologists is greatly needed to establish earlier PsA diagnoses and adequate multidisciplinary management.

Epidemiologia de pacientes queimados atendidos no Hospital de Clínicas da Universidade Federal de Uberlândia no período 2000-2001 / Epidemiology of burnerd patients attended at the Hospital de Clínicas da Universidade Federal de Uberlândia between 2000-2001

Duzentos e setenta e oito pacientes queimados atendidos no período de abril de 200 a março 2001 no Hospital de Clínicas da Faculdade de Medicina de Uberlândia, MG, Brasil foram analisados quanto à idade, sexo, profundidade, causas e localização das lesões. A média de idade foi 22,66 anos, sendo que 29,85% e 24,46% eram crianças menores de 16 anos e adultos entre 31 e 40 anos de idade, respectivamente. Homens (61,15%) se queimaram mais do que mulheres. Fogo por líquidos inflamados e líquidos aquecidos foram os agentes causadores de queimaduras mais freqüentes, 25,54% e 21,22%, respectivamente. A maioria das lesões foi de primeiro grau isoladas ou, de primeiro e segundo grau combinados. Os membros superiores e os olhos foram os locais do corpo mais susceptíveis a queimaduras. Esses dados têm que ser usados em prol do desenvolvimento de um programa de prevenção entre escolares e membros da comunidade e serem veiculados na mídia.

Two hundred seventy-eight patients of burn injuries treated over one year (April 2000 – March 2001) at the Hospital de Clínicas da Faculdade de Medicina de Uberlândia, MG, Brasil were analyzed according to age, sex, depth, causes and site of ijnury. The mean age was 22.66 years, 29.85% were children inder 16 years old, 24.46% were patients between 31-40 years old. Men (61.15%) are more susceptible to burns than women. Flammable liquids (25.54%) followed by scalds (21.22%) are the most common agents of burns. The majorite the injuries are either isolated first-degree burns or combined first and second degree. The upper limb and the eyes are the most frequent áreas of burn injuries. Parents can play and important role in prevention of burns in children, who are most susceptible to burns. These data must be used to develop prevention programs among school children and community members through media campaigns.
