[Pathologic diagnosis and subtyping of lymphoma in bone marrow biopsies using histologic examination, immunohistochemistry and gene rearrangement studies].

Objective: To assess the value of histologic examination, immunohistochemistry and gene rearrangement studies in the diagnosis and subtyping of lymphoma with bone marrow involvement (BMI).

Methods: Sixty-two formalin fixed, paraffin embedded bone marrow biopsy specimens were studied. Immunohistochemical and immunoglobulin heavy chain (IgH) and T-cell receptor gene rearrangement studies were performed in each case.

[The diagnosis and differential diagnosis of histiocytic necrotizing lymphadenitis. A study of histology, immunohistochemistry and electron microscopy].

Objective: To study the diagnosis and differential diagnosis of histiocytic necrotizing lymphadenitis (Kikuchi disease, KD).

Methods: Histologic analysis and immunohistochemical study (EnVision method) was carried out in 46 cases of KD, 5 cases of nonspecific lymphadenitis (NLD), 5 cases of non-Hodgkin's lymphoma (NHL), 5 cases of Hodgkin's lymphoma (HD), 5 cases of cat-scratch disease (CSD) and 5 cases of tuberculous lymphadenitis (TBL). Electron microscopy was also performed in 6 cases of KD and 2 cases of NHL.

Surgical treatment and follow-up results of pituitary ACTH microadenoma: 18 years' experience.

Objective: To review retrospectively our clinical experience with surgical treatment and follow-up of pituitary adrenocorticotropic hormone (ACTH) microadenomas at Rui Jin Hospital of Shanghai Second Medical University.

Methods: Eighty-seven patients with ACTH microadenomas underwent surgery via the transsphenoidal approach. Preoperative computed tomography and/or magnetic resonance imaging revealed microadenomas in only 46 patients and was negative in the remaining 41 patients, which were classified as microadenoma grade 0.

[Dynamic observation of the fibronectin content in plasma and subeschar tissue following burn].

Plasma and subeschar Fn levels were measured by one-dimension rocket immunoelectrophoresis and hemagglutination assay. In 16 healthy individuals, the mean value of plasma Fn was 318.7 +/- 82 micrograms/ml.
