Mucinous Cystadenoma Arising in a Uterine Isthmocele: A Case Report / Cistadenoma mucinoso surgindo em istmocele uterina: relato de caso

Abstract Isthmocele is a discontinuation of the myometrium at the uterine scar site in a patient with a previous cesarian section (CS). The cause of isthmocele appears to be multifactorial. Poor surgical technique, low incision location, uterine retroflection, obesity, smoking, inadequate healing of scars, and maternal age are possible related factors. Most patients with this condition are asymptomatic. However, women can present with postmenstrual bleeding, pelvic pain, subfertility, dysmenorrhea, infertility, and scar abscess. Brazil has one of the world s highest cesarean section rates. One of the consequences of the rising rate of CS is the isthmocele, an emerging female health problem. Here we report a case of mucinous cystadenoma arising in a uterine isthmocele, a complication, as far as we could investigate, not yet described in the literature.

Resumo Istmocele é a descontinuidade do miométrio no local da cicatriz uterina em paciente com cesariana anterior. A causa da istmocele parece ser multifatorial. Má técnica cirúrgica, baixa localização da incisão, retroflexão uterina, obesidade, tabagismo, cicatrização inadequada de cicatrizes e idade materna são possíveis fatores relacionados. A maioria dos pacientes com esta condição é assintomática. No entanto, as mulheres podem apresentar sangramento pós-menstrual, dor pélvica, subfertilidade, dismenorreia, infertilidade e abscesso cicatricial. O Brasil tem uma das maiores taxas de cesariana do mundo. Uma das consequências da taxa crescente de cesarianas é a istmocele, um problema emergente de saúde feminina. Aqui relatamos um caso de cistoadenoma mucinoso originado em uma istmocele uterina, uma complicação ainda não descrita, até onde pudemos investigar.

Manejo clínico e obstétrico em gestantes portadoras de hepatite autoimune complicada pela plaquetopenia moderada ou grave / Clinical and obstetrical management of pregnant women with autoimmune hepatitis complicated by moderate or severe thrombocytopenia

OBJETIVO: O presente trabalho tem como objetivo descrever o manejo do pré-natal e do parto em pacientes portadoras de hepatite autoimune associada à plaquetopenia moderada ou grave. MÉTODOS: Este trabalho foi realizado em hospital universitário, de nível terciário. Foram analisadas, retrospectivamente, 13 gestações em dez pacientes com diagnóstico de hepatite autoimune complicadas pela plaquetopenia. Os critérios de inclusão foram: diagnóstico clínico de hepatite autoimune, plaquetopenia moderada ou grave (contagem de plaquetas < 100 x 103/mm3), idade gestacional ao nascimento acima de 22 semanas e pacientes acompanhadas por equipe especializada da instituição. As variáveis estudadas incluíram idade materna, paridade, os regimes de tratamento, contagem de plaquetas, exames para investigação da função hepática, tipo de parto, peso ao nascer e idade gestacional no momento do parto. RESULTADOS: A média da idade materna foi de 24,5 anos (DP = 5,3) e seis (50%) ocorreram em nulíparas. Durante a gravidez, a monoterapia com prednisona foi adotada em 11 (92%) casos. De acordo com o perfil de autoanticorpos, sete (58%) gestações possuíam diagnóstico de hepatite autoimune tipo I, duas (17%) do tipo II e três (25%) eram portadoras de hepatite crônica criptogênica (títulos de autoanticorpos indetectáveis). A hipertensão portal foi caracterizada em 11 (92%) gestações. A idade gestacional média no parto foi de 36,9 semanas (DP = 1,5 semana), com média de peso ao nascer de 2446g (DP = 655g), sendo oito (67%) pequenos para a idade gestacional. No momento do parto, a plaquetopenia grave foi caracterizada em quatro (33%) casos e a cesárea foi realizada em sete (58%). As complicações no parto ocorreram em três casos (25%), uma paciente apresentou atonia uterina e duas, hematoma perineal. Não houve morte materna ou perinatal. CONCLUSÃO: As complicações em pacientes plaquetopênicas com hepatite autoimune são elevadas, no entanto, com os cuidados e atenção necessários, podem ser contornáveis. A associação de duas patologias graves parece aumentar o risco de prematuridade e restrição do crescimento fetal, demandando atenção pré-natal especializada, bem como vigilância do bem-estar do concepto.

OBJECTIVE: To describe the management of prenatal care and delivery in patients bearing autoimmune hepatitis associated with moderate or severe thrombocytopenia. METHODS: This study was performed in a tertiary level university hospital. Thirteen pregnancies in ten patients diagnosed with autoimmune hepatitis, complicated by thrombocytopenia, were retrospectively analyzed. The inclusion criteria were as follows: clinical diagnosis of autoimmune hepatitis, moderate or severe thrombocytopenia (platelet count < 100 x 103/mm3), gestational age at birth over 22 weeks, and patient followed-up by a specialized team at the institution. The variables studied were: maternal age, parity, treatment regimen, platelet count, examinations for investigation of hepatic function, type of delivery, weight at birth, and gestational age at the time of delivery. RESULTS: The average maternal age was 24.5 years (SD = 5.3) and six (50%) occurred in nulliparous women. During pregnancy, monotherapy with prednisone was adopted in 11 cases (92%). According to the autoantibody profiles, seven pregnancies (58%) had the autoimmune hepatitis type I diagnosis, two pregnancies had type II (17%), and three pregnancies (25%) had cryptogenic chronic hepatitis (undetectable titers of autoantibodies). Portal hypertension was featured in 11 pregnancies (92%). The average gestational age at delivery was 36.9 weeks (SD = 1.5 weeks), with an average weight at birth of 2,446 g (SD = 655 g). Eight infants (67%) were small for gestational age. At the time of delivery, severe thrombocytopenia was featured in four cases (33%) and cesarean surgery was performed in seven cases (58%). Complications at delivery occurred in three cases (25%), one patient presented uterine atony, and two patients presented perineal bruising. There was no perinatal or maternal death. CONCLUSION: The complications of thrombocytopenic patients with autoimmune hepatitis are elevated; nevertheless, with appropriate attention and care, they can be resolved. The association between two severe pathologies appears to increase the risk of prematurity and fetal growth restriction, demanding specialized prenatal care, as well as surveillance of newborn well-being.

Wilson's disease: an analysis of 28 Brazilian children

OBJECTIVES: Clinical-laboratory and evolutionary analysis of twenty-eight patients with Wilson's disease. METHODS: Twenty-eight children (twelve females and sixteen males) with Wilson's disease were evaluated retrospectively between 1987 and 2009, with a follow-up of 72 months (1 - 240 months). The clinical, laboratory, and histologic features at diagnosis were recorded at the end of the study. RESULTS: The median age at diagnosis was 11 years (2 - 18 years). Twelve patients were asymptomatic, seven had hepatitis symptoms, five had raised aminotransferase levels, three had hepatomegaly associated with neurological disorders, one had fulminant hepatitis with hemolytic anemia, and six patients presented with a Kayser-Fleischer ring. A histological analysis revealed that six children had chronic hepatitis, seven had cirrhosis, two had steatosis, one had portal fibrosis, and one had massive necrosis. The treatment consisted of D-penicillamine associated with pyridoxine for 26 patients. Adverse effects were observed in the other two patients: one presented with uncontrollable vomiting and the other demonstrated elastosis perforans serpiginosa. At the end of the study, all 26 treated patients were asymptomatic. Twenty-four of the patients were treated with D-penicillamine and pyridoxine, and two were treated with trientine and zinc sulfate. A liver transplant was performed in one patient with fulminant hepatitis, but the final patient died 48 hours after admission to the intensive care unit. CONCLUSIONS: Family screenings associated with early treatment are important in preventing Wilson's disease symptoms and potentially fatal disease progression. The study suggests that Wilson's disease must be ruled out in children older than two years presenting with abnormal levels of hepatic enzymes because of the heterogeneity of symptoms and the encouraging treatment results obtained so far.
