ABSTRACT

Objetivo: identificar mediante análise macroscópica e ra-diográfica as alterações estruturais em tecidos dentários afetados pela hiperbilirrubinemia, normalmente constatada a partir do sinal clínico de icterícia e provoca o desenvolvi-mento de pigmentos intrínsecos esverdeados nas estruturas dentárias. Materiais e Métodos: a amostra foi composta por 31 dentes decíduos dividida em grupo controle (n= 7) e grupo experimental (n= 24). As análises macroscópicas foram efetuadas por meio de fotografias individuais padroniza-das e as radiográficas obtidas com aquisições de imagem a 9 mA, 70 kVp, distância de 8cm, exposição 0,4 segundos e com XDR Sensor®. As imagens foram convertidas pelo software XDR Brasil 3.1.6 e padronizadas pelo programa GIMP 2.10.22. Os dados da média simples do histograma foram analisados pelo teste T-Student e Mann-Whitney (p<0,05). Resultados: demonstraram a maior intensidade de pigmentação em região cervical da raiz, com diferença de densidade radiográfica estaticamente significante na porção radicular entre os grupos experimental e controle (p=0,043). Na análise da densidade radiográfica da estrutura radicular do grupo experimental houve diferença estatica-mente significante (p=0,016) entre os terços cervical e apical. Discussão: Os dados evidenciaram que dentes pigmentados pela hiperbilirrubinemia não possuem alterações na densidade mineral nos terços coronários. Conclusão: Dentes com pigmentação esverdeada bilirrubina possuem diferenças na densidade radiográfica so-mente na região radicular.


Aim: is to identify, through macroscopic and radio-graphic analysis, structural changes in dental tissues affected by hyperbilirubinemia, usually seen from the clinical sign of icterus and causes the development of intrinsic greenish pigments in dental structure. Materials and Methods: The sample consisted of 31 primary teeth divided into a control group (n=7) and an experimental group (n=24). Macroscopic analyzes were performed using standardized individual photographs and radiographic ones obtained by image acquisition at 9 mA, 70 kVp, 8cm distance, 0.4 seconds exposure and with XDR Sensor®. The images were converted by XDR Brasil 3.1.6 software and standardized by GIMP 2.10.22 software. The Histogram's simple mean data were analyzed by T-Student and Mann-Whitney tests (p<0.05). Results: showed intensity of pigmentation in the cervical region of the root, with a statistically significant difference in the root portion between the experimental and control groups (p=0.043. In the analysis of radiographic density of the root structure of the experimental group, there was a statistically significant difference (p= 0.016) between the cervical and apical thirds. Discussion: The data showed that teeth pigmented by hyperbilirubinemia do not have changes in mineral density in the coronary thirds. Conclusion: Greenish pigments teeth have differences in radiographic density only in the root structure.

ABSTRACT

OBJECTIVE: A high prevalence of obesity is reported in children and adolescents with autoimmune hepatitis (AIH). Adipokines participate in inflammatory processes. The objective of this study was to examine the relationship between excess weight and systemic inflammation, adipokines, and ghrelin in adolescents with AIH. METHOD: This case-controlled study included 27 adolescents with AIH (13 with excess weight and 14 with normal weight) and a control group. Excess weight was defined by a body mass index/age Z score >+1 standard deviation. Adipokines (adiponectin, leptin, tumor necrosis factor alpha, interleukin 6 [IL-6], and IL-10) and ghrelin were measured with Luminex technology. RESULTS: Adiponectin (µg/mL) was higher (P < 0.001) in AIH adolescents with and without excess weight (median: 35.0 and 42.1, respectively) than in normal-weight (17.5) and excess-weight (17.0) controls. Leptin was higher (P < 0.001) in excess-weight AIH patients (18.0 ng/mL) and controls (19.8 ng/mL) than in normal-weight AIH (7.7 ng/mL) and control (7.0 ng/mL) adolescents. IL-6 levels were higher in excess-weight (3.8 pg/mL) and normal-weight (3.8 pg/mL) AIH patients than in excess-weight (1.1 pg/mL) and normal-weight (0.5 pg/mL) controls. IL-10 levels were higher (5.2 pg/mL) in normal-weight AIH patients than in excess-weight (1.8 pg/mL) and normal-weight (2.1 pg/mL) controls. Ferritin levels were lower in patients with AIH than in controls. CONCLUSIONS: Independent of body weight, AIH patients had higher levels of adipokines, especially adiponectin and IL-6. Leptin levels were associated with body weight and were not influenced by AIH. IL-10 levels were associated with lean tissue in AIH.

ABSTRACT

BACKGROUND: Portal hypertension is one of the complications of cirrhosis and is associated with numerous systemic manifestations, including renal, brain, pulmonary, cardiac and vascular changes. In routine ophthalmological examinations performed at our service, we observed that some children diagnosed with portal hypertension had increased retinal vascular tortuosity. OBJECTIVE: 1. To evaluate the presence of retinal vascular abnormalities (vascular tortuosity) in children diagnosed with portal hypertension; 2. To investigate the association between retinal vascular tortuosity and the presence of gastroesophageal varices in these children; 3. To evaluate the use of clinical and laboratory parameters to predict the presence of gastroesophageal varices in children with portal hypertension. METHODS: This was a cross-sectional and observational study that included patients aged <18 years with a diagnosis of portal hypertension. The participants included were submitted to dilated fundus examination and fundus photography with Visucam (Carl Zeiss Meditec AG) device. Besides, clinical and laboratorial data were collected from the patients' medical records. RESULTS: A total of 72 patients were included in this study, and 36% of them had an increase in retinal vascular tortuosity. Platelet count (P=0.001), bilirubin dosage (P=0.013) and aspartate transaminase dosage (AST) (P=0.042) were associated with the presence of gastroesophageal varices in digestive endoscopy. There was no association between retinal vascular tortuosity and the presence of gastroesophageal varices (P=0.498). CONCLUSION: The results of this study suggest that platelet count, bilirubin dosage, and aspartate transaminase dosage were associated with the presence of gastroesophageal varices in digestive endoscopy. Regarding the retinal findings, we found that there was an increase in retinal vascular tortuosity in 36% of pediatric patients, but no association was found with the presence of gastroesophageal varices.

RESUMO CONTEXTO: A hipertensão portal é uma das complicações da cirrose e está associada a inúmeras manifestações sistêmicas, incluindo alterações renais, cerebrais, pulmonares, cardíacas e vasculares. Nos exames oftalmológicos de rotina realizados em nosso serviço, observamos que algumas crianças diagnosticadas com hipertensão portal apresentaram aumento da tortuosidade vascular da retina. OBJETIVO: 1. Avaliar a presença de anormalidades vasculares da retina (tortuosidade vascular) em crianças diagnosticadas com hipertensão portal; 2. Investigar a associação entre tortuosidade vascular da retina e presença de varizes gastroesofágicas nessas crianças; 3. Avaliar o uso de parâmetros clínicos e laboratoriais para prever a presença de varizes gastroesofágicas em crianças com hipertensão portal. MÉTODOS: Estudo transversal e observacional, que incluiu pacientes com idade <18 anos com diagnóstico de hipertensão portal. Os participantes incluídos foram submetidos ao exame de fundo de olho dilatado e fotografia de fundo com dispositivo Visucam (Carl Zeiss Meditec AG). Além disso, foram coletados dados clínicos e laboratoriais dos prontuários dos pacientes. RESULTADOS: Um total de 72 pacientes foi incluído neste estudo e 36% deles apresentaram aumento da tortuosidade vascular da retina. Contagem de plaquetas (P=0,001), dosagem de bilirrubina (P=0,013) e dosagem de aspartato transaminase (AST) (P=0,042) foram associados à presença de varizes gastroesofágicas na endoscopia digestiva. Não houve associação entre tortuosidade vascular da retina e presença de varizes gastroesofágicas (P=0,498). CONCLUSÃO: Os resultados deste estudo sugerem que a contagem de plaquetas, a dosagem de bilirrubina e a aspartato transaminase foram associadas à presença de varizes gastroesofágicas na endoscopia digestiva. Em relação aos achados da retina, descobrimos que houve um aumento na tortuosidade vascular da retina em 36% dos pacientes pediátricos, mas nenhuma associação foi encontrada com a presença de varizes gastroesofágicas.

ABSTRACT

OBJECTIVE: To report a case of severe dystrophic calcification in maxillary sinus of a child with liver transplantation and dental organs pigmented by hyperbilirubinemia. CASE DESCRIPTION: female patient, 12 years old, with liver transplantation performed at the age of 7 due to extrahepatic biliary atresia (EHBA). The patient was receiving the immunosuppressant tacrolimus (2 mg daily). Intraoral clinical exam showed tooth green pigmentation by bilirubin. Cone-beam volumetric computed tomography (CT) was performed to verify radiographic density of pigmented dental elements. Hounsfield scale measurement did not show changes in radiographic density of dental structures. However, CT scan showed intense dystrophic calcification in the maxillary sinus region. COMMENTS: CT scan indicated relevant radiographic findings, with radiopacity of the maxillary sinus due to fungal or non-fungal sinusitis. This case report highlights the presence of radiographic image associated with acute infectious processes that could compromise the systemic state of immunosuppressed patients.


OBJETIVO: Relatar um caso de calcificação distrófica intensa no interior do seio maxilar em uma criança com transplante hepático e órgãos dentais pigmentados por hiperbilirrubinemia. DESCRIçÃO DO CASO: Paciente do sexo feminino, 12 anos de idade, com transplante hepático efetuado aos 7 anos de vida devido à atresia de vias biliares extra-hepática, uso de tacrolimus imunossupressor (2 mg diários). No exame clínico intrabucal, observou-se a presença de pigmentação esverdeada no órgão dental por bilirrubina. Efetuou-se um exame de tomografia computadorizada volumétrica de feixe cônico para análise da densidade radiográfica dos elementos dentais pigmentados. Mediante interpretação da imagem pela escala de Hounsfield, não foi constatada nenhuma alteração na densidade radiográfica das estruturas do órgão dental. No entanto, a tomografia computadorizada evidenciou a presença de calcificação distrófica intensa em região de seio maxilar. COMENTÁRIOS: A alteração de imagem observada no exame de tomografia computadorizada demonstrou achado radiográfico relevante, com presença de radiopacidades no interior do seio maxilar decorrentes de sinusites fúngicas ou não fúngicas. O relato desse caso é relevante por apresentar alteração de imagem radiográfica exacerbada associada a quadros infecciosos agudos que podem comprometer o estado sistêmico do paciente imunossuprimido.

ABSTRACT

PURPOSE:: To analyze the use of this sponge in pediatric patients undergoing split-liver transplantation. METHODS:: Retrospective study, including 35 pediatric patients undergoing split-liver transplantation, divided into two groups according to the use of the sponge: 18 patients in Group A (no sponge) and 17 in Group B (with sponge). RESULTS:: The characteristics of recipients and donors were similar. We observed greater number of reoperation due to bleeding in the wound area in Group A (10 patients - 55.5%) than in Group B (3 patients - 17.6%); p = 0.035. The median volume of red blood cells transfused in Group A was significantly higher (73.4 ± 102.38 mL/kg) than that in Group B (35.1 ± 41.67 mL/kg); p = 0.048. Regarding bile leak there was no statistical difference. CONCLUSION:: The use of the human fibrinogen and thrombin sponge, required lower volume of red blood cell transfusion and presented lower reoperation rates due to bleeding in the wound area.

ABSTRACT

Pruritus represents one of the main clinical complaints in medical practice, and leads to significant impairment of life quality and some discomfort. Although the knowledge of its main primary and secondary etiologies is well-established in Internal Medicine, especially in Hepatology, its pathophysiological basis and specific therapeutic-directed approaches are still very complex and need a proper systematization for comprehension. This review aims to present the main current themes regarding the main clinical, pathophysiological, therapeutical and management aspects of cholestasis-associated pruritus. METHODS: The authors performed a wide review of practical clinical guidelines, review articles and original articles from manuscripts published and indexed in PubMed. CONCLUSIONS: Pruritus in cholestasis represents a complex symptom in clinical practice and can be secondary to different pathophysiological mechanisms; its early recognition allows a proper therapeutic approach in most cases.


O prurido representa uma das principais queixas clínicas na prática médica e origina importante comprometimento da qualidade de vida, além de desconforto. Apesar de suas principais etiologias primárias e secundárias serem de conhecimento bem estabelecido na Clínica Médica, em especial na Hepatologia, suas bases fisiopatológicas e os princípios da terapêutica específica direcionada são bastante complexos e necessitam uma sistematização adequada para sua compreensão apropriada. Esta revisão objetiva abordar os principais temas atuais referentes às bases clínicas, fisiopatológicas, terapêuticas e de manejo do prurido relacionados à colestase. Os autores realizaram ampla revisão em diretrizes clínicas práticas, artigos de revisão e publicações originais de artigos publicados e indexados na base PubMed. O prurido na colestase representa um sintoma complexo na prática clínica e pode decorrer de diferentes mecanismos fisiopatológicos secundários. Seu reconhecimento precoce possibilita a abordagem terapêutica apropriada na maioria dos casos.

ABSTRACT

ABSTRACT Background: Surgical strategy to increase the number of liver transplants in the pediatric population is the ex-situ liver transection (reduction or split). However, it is associated with complications such as hemorrhage and leaks. The human fibrinogen and thrombin sponge is useful for improving hemostasis in liver surgery. Aim: Compare pediatric liver transplants with ex-situ liver transection (reduction or split) with or without the human fibrinogen and thrombin sponge. Methods: Was performed a prospective analysis of 21 patients submitted to liver transplantation with ex-situ liver transection with the application of the human fibrinogen and thrombin sponge in the wound area (group A) and retrospective analysis of 59 patients without the sponge (group B). Results: The characteristics of recipients and donors were similar. There were fewer reoperations due to bleeding in the wound area in group A (14.2%) compared to group B (41.7%, p=0.029). There was no difference in relation to the biliary leak (group A: 17.6%, group B: 5.1%, p=0.14). Conclusion: There was a lower number of reoperations due to bleeding of the wound area of ​​the hepatic graft when the human fibrinogen and thrombin sponge were used.

ABSTRACT

Doença hepática crônica definida como lesão inflamatória do fígado, apresenta etiologias e graus de necrose e inflamação hepatocelular variados. Essas hepatopatias causam modificações bucais e sistêmicas pouco relatadas na literatura odontológica. Alterações na cavidade bucal como a pigmentação esverdeada de tecidos duros e moles, hipoplasia de esmalte e hipocalcificação são notadas em crianças com doença hepática crônica de tenra idade. Concomitante a essas mudanças observa-se algumas manifestações sistêmicas características, como a icterícia, xantomas e hepatoesplenomegalia. Dentre as opções terapêuticas para crianças com doença hepática crônica encontra-se o transplante hepático. Porém, para que se ocorra o ato cirúrgico é fundamental a intervenção do profissional da área odontológica, a fim de se eliminar e prevenir surgimento de focos infecciosos. Dessa forma, o presente trabalho oferece ao cirurgião dentista, em especial ao odontopediatra subsídios científicos para o diagnóstico e intervenção do profissional em crianças com doença hepática crônica.


Chronic liver disease defined as an inflammatory injury of the liver presents etiologies, varied necrosis degrees and hepatic cell inflammation. Those liver diseases result in oral and systemic findings seldom mentioned in the literature of dentistry. Mouth alterations such as green staining of hard and soft tissue, hypoplasia of enamel and hypocalcification changes are constantly seen in children. Concomitant to those changes it is possible to observe some systemic manifestations which are characteristics, such as jaundice, xanthoma and hepatosplenomegaly. Among the therapeutic options for children with chronic liver disease, there is the liver transplant. However for complete success of this surgical procedure it is extremely important the intervention of the dental surgery, in order to eliminate and prevent focus of infection. Based on that, the current study offers to the dentist and in special to the pedodontist, important scientific support for the diagnosis and intervention of these professionals in children with chronic liver disease.

OBJECTIVE: To evaluate food intake, occurrence of energy-protein malnutrition and anemia, and intestinal iron absorption in children with chronic liver disease. METHODS: The study included 25 children with chronic liver disease, 14 with cholestasis and 11 without cholestasis. The age varied between 6.5 months and 12.1 years. Intestinal iron absorption was evaluated by the increment of serum iron one hour after the ingestion of 1 mg/kg of elemental iron and by the response to oral iron therapy. Iron intestinal absorption was compared to a group with iron deficiency anemia (without liver disease). RESULTS: The mean intake of energy and protein in the cholestatic group was higher than in patients without cholestasis. The nutritional deficit was more severe in cholestatic patients, especially with regard to height-for-age and weight-for-age indices. Anemia was found in both cholestatic group (11/14; 78.6%) and noncholestatic group (7/11; 63.6%). The cholestatic group presented lower (p < 0.05) intestinal iron absorption (90.6+/-42.1 microg/dl) than the iron deficiency anemia group (159.6+/-69.9 microg/dl). However, cholestatic patients responded to oral iron therapy. The noncholestatic group showed intestinal iron absorption similar to the iron deficiency anemia group. CONCLUSION: The cholestatic group showed more severe nutritional deficits. Despite the evidence of lower iron intestinal absorption, cholestatic patients responded to oral iron therapy, probably, due to the coexistence of iron deficiency.

ABSTRACT

OBJETIVO: Avaliar a ingestão alimentar, a ocorrência de desnutrição energético-protéica e de anemia e a absorção intestinal de ferro em crianças com doença hepática crônica. CASUíSTICA E MÉTODOS: Foram estudados 25 pacientes com doença hepática crônica, sendo 15 com colestase e 11 sem colestase. A idade variou entre 6,5 meses e 12,1 anos. A absorção intestinal de ferro foi avaliada pela elevação do ferro sérico uma hora após a ingestão de 1 mg/kg de ferro elementar e pela resposta à ferroterapia oral. A absorção intestinal de ferro foi comparada com um grupo de crianças com anemia ferropriva. RESULTADOS: A ingestão média de energia e proteínas nos pacientes com doença hepática com colestase foi maior do que nos pacientes sem colestase. O déficit nutricional foi mais grave nos pacientes com colestase, predominando os déficits de estatura-idade e peso-idade. A anemia foi freqüente tanto nas crianças com doença hepática com colestase (11/14; 78,6 por cento) como nas sem colestase (7/11; 63,6 por cento). Na doença hepática com colestase, observou-se menor (p < 0,05) absorção intestinal de ferro (90,6±42,1 µg/dl), em comparação com o grupo com anemia ferropriva (159,6±69,9 µg/dl). No entanto, o grupo com colestase apresentou resposta à ferroterapia oral. Os pacientes com doença hepática sem colestase apresentaram absorção intestinal de ferro semelhante à das crianças com anemia ferropriva. CONCLUSÃO: A doença hepática crônica com colestase associa-se com maior comprometimento nutricional. Apesar das crianças com colestase apresentarem evidência de má absorção intestinal de ferro, apresentaram resposta à ferroterapia oral, provavelmente, pela coexistência de deficiência de ferro.
