Toxic epidermal necrolysis (TEN) is a rare condition, causing life‐threatening adverse cutaneous reactions. TEN occurrence after bone marrow transplantation (BMT) is a well‐known phenomenon; however, to date, only a few cases have been reported in the published work. Here, we describe the case of a 53‐year‐old woman who experienced TEN after undergoing allogenic BMT for malignant lymphoma. Skin erosion spread across a maximum of 70% of the body surface area and severe mucosal lesions developed. Steroid pulse therapy, plasma apheresis and immunoglobulin therapy were administrated, which resulted in the complete resolution of TEN. However, she developed hemophagocytic lymphohistiocytosis and died 38 days after BMT, owing to rupture of the lower digestive tract complicated by multi‐organ failure. In our case, engraftment failure occurred, and the peripheral white blood cell count was less than 100/μL during the TEN course, suggesting that the presence of only a few immune cells could cause TEN. Our findings showed that high mortality rates and widespread skin erosion could be regarded as the most important characteristics of TEN occurring after BMT. 相似文献

Virus-associated hemophagocytic syndrome in an international traveler as a differential diagnosis of SARS 总被引:3,自引:0,他引:3
During the epidemic of severe acute respiratory syndrome in 2003, a 27-year- old Japanese woman presented a high fever and acute respiratory distress with pulmonary infiltrates after traveling to a high-risk area. An alternative diagnosis was made as Epstein-Barr virus-associated hemophagocytic syndrome, based on the proliferation of macrophages with hemophagocytosis in the bone marrow and Epstein-Barr viral marker profiles. Virus-associated hemophagocytic syndrome in an international traveler should be included in the differential diagnosis of severe acute respiratory syndrome. 相似文献

Ambulatory electrocardiographic monitoring was performed in 18 children with a congenital complete heart block (CCHB). They had no cardiac structural anomalies. These patients could be divided into 3 groups according to the pattern of fluctuations in beat-to-beat ventricular rates. Type 1 patients showed rapid and transient fluctuations and demonstrated a high correlation between atrial and ventricular rates. Type 3 patients showed a constant ventricular rate and little variation through the 24 hour period and there was no appreciable correlation between atrial and ventricular rates. Twelve of 18 patients had additional arrhythmias. A few sporadic ventricular premature contractions (VPCs) were found in 9 patients, and bigeminy of VPCs or ventricular tachycardias were seen in 2 patients during exercise. Frequent and sudden prolongation of RR intervals was found during sleep in 3 patients. The longest intervals of ventricular asystoles were 7.2, 3.2 and 3.2 sec, respectively. The mechanism of this phenomenon appeared to be not only an exit block, but also arrest or a lack of automaticity of a subsidiary pacemaker. One of these patients developed frequent Stokes-Adams attacks. Type 3 patients with sudden prolongation of RR intervals and/or frequent ventricular arrhythmias should be under careful observation. Ambulatory electrocardiographic monitoring is recommended for children with CCHB for evaluation of potential risk factors for Stokes-Adams attacks. 相似文献

A Large Retroperitoneal Encapsulation of Bile from a Spontaneous Perforation of the Common Bile Duct
Katsusuke Satake M.D. F.A.C.S. Teruyuki Ikehara M.D. Keiho Shim M.D. Tsuyoshi Asai M.D. Kaoru Umeyama M.D. Michio Yoshioka Hiroshi Takemura M.D. 《The American journal of gastroenterology》1985,80(4):279-283
We report a patient with spontaneous rupture of the common bile duct. This is an extremely rare condition which produces free leakage of bile into the peritoneal cavity. There has been no previous report concerning the formation of a large retroperitoneal encapsulation of bile. The preoperative diagnosis in our patient was very difficult and endoscopic retrograde pancreatocholangiography and cystography by ultrasound guidance were helpful. 相似文献
