RECOMMENDATIONS FOR INVASIVE PROCEDURES IN PATIENTS WITH DISEASES OF THE LIVER AND BILIARY TRACT: REPORT OF A JOINT MEETING OF THE BRAZILIAN SOCIETY OF HEPATOLOGY (SBH), BRAZILIAN SOCIETY OF DIGESTIVE ENDOSCOPY (SOBED) AND BRAZILIAN SOCIETY OF INTERVENTIONAL RADIOLOGY AND ENDOVASCULAR SURGERY (SOBRICE).

Liver and biliary tract diseases are common causes of morbidity and mortality worldwide. Invasive procedures are usually performed in those patients with hepatobiliary diseases for both diagnostic and therapeutic purposes. Defining proper indications and restraints of commonly used techniques is crucial for proper patient selection, maximizing positive results and limiting complications. In 2018, the Brazilian Society of Hepato-logy (SBH) in cooperation with the Brazilian Society of Interventional Radiology and Endovascular surgery (SOBRICE) and the Brazilian Society of Digestive Endoscopy (SOBED) sponsored a joint single-topic meeting on invasive procedures in patients with hepatobiliary diseases. This paper summarizes the proceedings of the aforementioned meeting. It is intended to guide clinicians, gastroenterologists, hepatologists, radiologists, and endoscopists for the proper use of invasive procedures for management of patients with hepatobiliary diseases.

Yellow Nail Syndrome Associated with Pericarditis and Pericardial Effusion: a Case Report.

Yellow nail syndrome (YNS) is an uncommon condition characterized by nail changes, lymphedema, in addition to pulmonary disorders and pleural effusion. Pericarditis and non-cardiac disorders can evolve with pericardial effusions including autoimmune conditions, hypothyroidism, malignancies, tuberculosis, and uremia. A 72-year-old Brazilian woman under treatment for arterial hypertension and hypothyroidism was admitted with pericarditis and pericardial effusion concomitant with yellow nail syndrome. She denied tobacco smoking, alcohol abuse, and similar disorders in her family. Clinical and complementary evaluation ruled out infectious diseases, malignancies, and autoimmune disorders as etiologic factors in this case. Hypothyroidism is a well-known cause of pericardial effusion, the vast majority in the absence of pericarditis, and has been described as an associated condition in some individuals with YNS. Case studies might contribute to better understanding of these causal or casual relationships.

Expressão dos marcadores tumorais CD-34 e CASPASE-3 no carcinoma epidermóide de esôfago / CD-34 and CASPASE-3 biomarkers expression in esophageal epidermoid carcinoma

OBJETIVO: Analisar citofotometricamente a expressão do marcador de densidade microvascular CD-34 e de apoptose caspase-3 no carcinoma epidermóide de esôfago, e correlacionar os marcadores entre si. MÉTODOS: Análise imunoistoquímica de 29 peças cirúrgicas de carcinomas epidermóides de esôfago, baseada nos índices de marcagem dos anticorpos CD-34 e caspase-3, utilizando-se sistema de citofotometria computadorizada. Comparou-se a expressão quantitativa destes marcadores, a relação entre eles, a relação com a idade dos pacientes, tamanho das lesões e classificação TNM. RESULTADOS: O valor da mediana do índice de marcagem do CD-34 foi de 72,6 por cento e o da caspase-3 de 96,5 por cento. Não se obteve significância estatística na correlação destes marcadores com o tamanho tumoral ou com a idade dos pacientes. Houve discreta tendência à correlação positiva entre o CD-34 e a classificação TNM. O marcador caspase-3, apesar de apresentar maior índice de marcagem que o CD-34 nestes tumores, não revelou nenhuma correlação com as variáveis estudadas. A correlação entre o CD-34 e a caspase-3 apresentou tênue tendência positiva. CONCLUSÃO: Ambos os marcadores têm boa expressão no carcinoma epidermóide de esôfago, onde o CD-34 tem menor expressividade que a caspase-3 e os mesmos não apresentam correlação entre si.

OBJECTIVES: To analyze by cytophotometry study the expression of CD-34 angiogenesis and caspase-3 apoptosis markers in the esophagus squamous cell carcinoma and to correlate markers themselves. METHODS: Twenty-nine esophageal squamous cell carcinoma specimens were submitted to immunohystochemical analysis, based on label index of CD-34 and caspase-3 antibodies, using cytophotometry computer system. Variables considered in the correlation analysis were biomarkers expression quantification, patient age, lesion size, and TNM classification system. RESULTS: Index label median value for CD-34 was 72,6 percent and for caspase-3 represented 96,5 percent. Statistical significant correlation was not demonstrated between the respective biomarkers and lesion size (p=0,96) or patient age (p=0,95). There was a slightly tendency to a positive correlation between CD-34 index label and TNM classification system (p=0,11). Although presenting a higher index label than CD-34 marker (p=0,007), caspase-3 did not show any relationship with the studied variables (p>0,19). The correlation between CD-34 and caspase-3 presented a small positive tendency (r=0,09 and p=0,65). CONCLUSION: Both studied biomarkers showed good expression in esophageal squamous cell carcinoma, whereas CD-34 marker presented lower expression than caspase-3 in this specific tumor. The respective biomarkers do not demonstrate any correlation between themselves.
