As a model system for mucocutaneous lymph node syndrome (MCLS), we have advocated and used mice which had been rendered tolerant to Streptococcus pyogenes-associated antigens by neonatal infection with group A fteta-hemolytic streptococci, because these mice have shown a variety of peculiar bioimmunological characteristics bearing a striking resemblance to those of MCLS patients. The results of our current investigations reaffirmed the reliability of the animal model by indicating that mice subjected to neonatal infection with 5. pyogenes , or inoculation with streptococcal pyrogenic exotoxin (SPE) in Freund's adjuvant, were perfect counterparts of patients with MCLS on account of their platelet activation and hyperaggregability in response to provocative treatment, which are familiar findings in this disease. 相似文献

A lymph node metastasis in the neck or parotid region from an unknown primary melanoma is an uncommon occurrence. Out of a total of 300 patients with head and neck melanoma treated at the Netherlands Cancer Institute between 1976 and 1992, 17 (5.7%) presented in this way. The most common site for metastatic lymph nodes (18 nodes in 17 patients) was level V (n= 7), followed by the parotid region (n= 4), level II (n= 4), level III (n= 2), and level IV (n= 7). Two patients had local excision of the neck node metastasis only, while the remaining 15 patients underwent more extensive surgical treatment. The 5-year disease-specific survival rate in this group was 48%, with a median survival of 36 months, which is more or less similar to the prognosis of stage II melanoma of the head and neck with a known, surgically treated primary tumour. No relation was found between disease-free interval and sex, the number of positive lymph nodes or the duration of symptoms. 相似文献

Fine-needle cytology of an eccrine spiradenoma of the breast: diagnosis made by a holistic approach.
Eccrine spiradenoma is a rather rare adnexal tumor of the skin. When the clinical presentation is that of a breast neoplasm, diagnosis can be difficult. As cytology was a new procedure for this tumor, the approach of choice appeared to be a holistic one. The cytologic picture showed bland groups of uniformly sized cuboid cells with scant cytoplasm, round to ovoid nuclei, and inconspicuous nucleoli, while in the groups rosettelike structures could be discerned. Only by integrating the data of clinical history, inspection, palpation, reaction on breast puncture, and immunologic findings could the diagnosis be made. 相似文献

Background: Percutaneous closed needle biopsy of musculoskeletal neoplasms has gained in popularity. However, it remains controversial
whether or not to resect the needle tract for fear of a local recurrence. A single published case report exists, noting the
lone tract recurrence of an extremity skeletal osteosarcoma.
Methods: We report on three additional individuals who demonstrated that tract local recurrences may occur after a closed needle biopsy
for nonosteosarcoma, nonextremity sarcomas. For perspective, the world literature is reviewed to identify tract recurrences
for other malignancies and the results of needle biopsy in musculoskeletal neoplasms.
Results: Eighty-nine percent of needle tract local recurrences occur when carcinomas are subjected to biopsy, as reported in the literature.
Forty-seven cases since 1950 are described representing essentially all tumor types. The nature of musculoskeletal neoplasms
makes closed biopsy more difficult than for softer, more homogeneous, and easier to access neoplasms.
Conclusions: Local recurrences of sarcoma may occur in closed needle biopsy tracts. Strong consideration should be given to open biopsy
and tract resection. 相似文献

Based upon detailed dissections of the lymphatic system in adult cadavers, the lymphatic drainage of the gallbladder was divided
into three pathways: (1) The cholecystoretropancreatic pathway, which had two routes, one running spirally from the anterior
surface of the common bile duct to the right rear, and the other running almost straight down from the posterior surface of
the common bile duct. These routes converged at the principal retroportal node at the posterior surface of the head of the
pancreas. (2) The cholecysto-celiac pathway; this was the route running to the left through the hepatoduodenal ligament to
reach the celiac nodes. (3) The cholecysto-mesenteric pathway; this was the route running to the left in front of the portal
vein to connect with the nodes at the superior mesenteric root. The cholecysto-retropancreatic pathway can be regarded as
the main pathway, and the principal retroportal node appeared to be critical as the main terminal node in the visceral lymphatic
system of the gallbladder. These three pathways converged with the abdomino-aortic lymph nodes near the left renal vein, and
the nodes in the interaortico-caval space were considered to be of particular importance.

A new radiolucent device for increased accuracy of CT-guided fine-needle punctures permits precise determination of the optimum
angle, depth, and position of the fine needle, which can be preset from the data supplied on the CT monitor. Puncture and
repeat scans for controlling the tip of the needle can be performed with the patient in a stationary position. The device
is designed as a belt that holds a needle holder sheath and a goniometric scale, both of which can be moved to varying positions
around the patient. 相似文献

目的 总结原位心脏移植术后急性排异反应的监测。方法 2000-01/2002-04施行11例原位心脏移植手术,结合临床表现、心电图、超声心动图、化验检查及心内膜活栓等检查,对心脏移植术后急性排异反应的监测进行分析。结果 采用临床症状+心电图+超声心电图+心肌血清学检测综合判断有6次急性排异反应,行心内膜活检证实Ⅰb级2次,Ⅲa级3次;术后常规行心内膜活检21次,仅发现急性排异反应Ⅰa或Ⅰb级5次。结论 急性排异反应是关系到心脏移植术后患者康复及愈后的重要因素,因此要及时、有效地进行监测;心内膜心肌活检是诊断急性排异反应敏感可靠的方法,但为有创性检查,有一定的并发症风险,其他多项无创性检查可作辅助指标,因此急性排异反应监测应把无创性检查与心内膜心肌活检有机地结合起来。 相似文献
