    ABSTRACT Objective: to describe the first 13 cases of laparoscopic correction of common bile duct cyst in the Pequeno Príncipe Hospital, Curitiba, Paraná, Brazil. Methods: we performed a retrospective analysis of medical records of cases of choledochal cyst operated by laparoscopy between March 2014 and September 2016. Results: of the 13 patients, eight were female and the mean age at surgery was 7.8 years. The most common symptom was abdominal pain. The hepaticoduodenal anastomosis was the most used reconstruction technique, in 84.6% of the cases. There was no conversion to laparotomy or intraoperative complications. Only one patient presented anastomotic fistula and was reoperated by laparotomy. All patients were followed up in an outpatient clinic, were asymptomatic and had no episode of cholangitis after surgery, with a mean follow-up of 16 months. Conclusion: laparoscopy is a safe method to correct choledochal cysts, even in younger children, with low rates of complications and low rates of conversion to open surgery when performed by well trained surgeons

    We present a case of trigeminal neuralgia with cranial normal magnetic resonance image (MRI) and computed tomography. The pain was not relieved by carbamazepine and microvascular decompression surgery was done. After two months the pain was similar to the condition before surgery. At this time, MRI showed an expansive lesion in Meckel's cave that was treated with radical resection by extra-dural approach. The pathologic examination revealed a primary melanoma. The follow-up after six months did not show abnormalities.<br>Apresentamos um caso de neuralgia do trigêmeo com investigação radiológica de ressonância magnética (RM) e tomografia computadorizada apresentando resultado normal. A dor não apresentou alívio com carbamazepina, sendo indicado descompressão microvascular do trigêmio. Passados dois meses, o paciente queixava-se de dor com intensidade similar à do pré-operatório. Nova RM mostrou lesão expansiva no cavo de Meckel, a qual foi tratada cirurgicamente por abordagem extra-dural. O exame anatomopatológico foi compatível com melanoma primário. O seguimento radiológico, após seis meses da cirurgia, não apresentou anormalidades

    Genome sequence of the gram-positive sugarcane pathogen Leifsonia xyli subsp. xyli

    The genome sequence of Leifsonia xyli subsp. xyli, which causes ratoon stunting disease and affects sugarcane worldwide, was determined. The single circular chromosome of Leifsonia xyli subsp. xyli CTCB07 was 2.6 Mb in length with a GC content of 68% and 2,044 predicted open reading frames. The analysis also revealed 307 predicted pseudogenes, which is more than any bacterial plant pathogen sequenced to date. Many of these pseudogenes, if functional, would likely be involved in the degradation of plant heteropolysaccharides, uptake of free sugars, and synthesis of amino acids. Although L. xyli subsp. xyli has only been identified colonizing the xylem vessels of sugarcane, the numbers of predicted regulatory genes and sugar transporters are similar to those in free-living organisms. Some of the predicted pathogenicity genes appear to have been acquired by lateral transfer and include genes for cellulase, pectinase, wilt-inducing protein, lysozyme, and desaturase. The presence of the latter may contribute to stunting, since it is likely involved in the synthesis of abscisic acid, a hormone that arrests growth. Our findings are consistent with the nutritionally fastidious behavior exhibited by L. xyli subsp. xyli and suggest an ongoing adaptation to the restricted ecological niche it inhabits
