干扰素在恶性淋巴瘤自体移植后早期干预的应用

目的:观察非霍奇金淋巴瘤（non-Hodgkin's lymphoma，NHL）患者自体造血干细胞移植（autologous hematopoietic stem cell transplantation，ASCT）术后应用重组人α-2b干扰素（α-2b IFN）进行早期干预治疗的临床疗效。方法:选取18例行ASCT的NHL患者为研究对象，移植前疾病评估均未达到完全缓解（complete remission，CR），试验组血象恢复后给予IFN 3 000 000 U次/隔日干预治疗，3个月后停用；对照组未行干扰素干预治疗，分析总体疗效及两组对比的生存情况。结果:随访中位时间为34（10~50）个月，患者中位生存时间为37（31~45）个月，3年总体无进展生存（progressive free survival，PFS）、总生存（overall survivial，OS）分别为54.7%、66.8%。ASCT后试验组1年内无疾病复发，2年内复发率为12.5%；对照组1年内复发率为20%，2年内复发率为30%。结论:NHL患者在ASCT后给予重组人α-2b IFN早期干预治疗，患者耐受性好，可能降低移植后早期复发率。     

Buscando o motivo da instabilidade hemodinâmica: relato de caso sobre o papel do ultrassom intraoperatório

Background and objectives

A prompt and effective management of trauma patient is necessary. The aim of this case report is to highlight the importance of intraoperative echocardiography as a useful tool in patients suffering from refractory hemodynamic instability no otherwise explained.

Erosive pustular dermatosis of the scalp in an adolescent with near‐total hair regrowth: Case report and review of the literature

Erosive pustular dermatosis of the scalp (EPDS) is an uncommon chronic inflammatory response to scalp trauma that usually resolves with cicatricial alopecia. It most commonly affects elderly patients with a history of actinic damage. Herein, we describe a 16‐year‐old girl with acrofacial dysostosis type 1 presenting after surgery with crusting purulent scalp lesions, whose clinical presentation and histopathologic findings were consistent with EPDS. A review of the literature on EPDS in children is also detailed.     

Direct insertion of an ultra‐slim upper endoscope for cholangioscopy in patients undergoing choledochoduodenostomy

Direct peroral cholangioscopy (POC) using an ultra‐slim upper endoscope is one modality of POC for intraductal endoscopic evaluation and treatment of the bile duct. Choledochoduodenostomy (CDS) is one modality of biliary bypass surgery that provides a new route to the bile duct. We carried out direct POC using an ultra‐slim upper endoscope without the use of accessories in 10 patients (four sump syndromes, three bile duct strictures and three intrahepatic duct stones) previously undergoing surgical CDS. Direct POC was successful in all patients. The use of an intraductal balloon catheter was required in one patient for advancement of the endoscope into the bile duct. Distal bile ducts with sump syndromes were cleared using baskets and water irrigation under direct POC. Cholangiocarcinoma was diagnosed in one patient with hilar bile duct stricture after cholangioscopic evaluation and a targeting forceps biopsy under direct POC. Intrahepatic duct stones were successfully extracted after intraductal fragmentation under direct POC. Oozing bleeding occurred during intraductal lithotripsy but stopped spontaneously. Direct POC using an ultra‐slim upper endoscope without the assistance of accessories can easily be carried out in patients undergoing CDS.
