Monoclonality of infiltrating plasma cells in primary pulmonary nodular amyloidosis: detection with polymerase chain reaction 下载免费PDF全文

AIMS: To investigate the relation between localised amyloidosis and immunocytic dyscrasia. METHODS: Open lung biopsy specimens from a 72 year old man with multiple nodules in the right middle and lower lung were stained with haematoxylin-eosin, Congo red, and antibodies against IgG, IgA, IgM, and kappa and lambda light chains. Semi-nested PCR amplification for the immunoglobulin heavy chain (IgH) gene was performed using consensus primers for the VDJ region of the IgH gene, FR3A, LJH, and VLJH. RESULTS: The biopsy specimens contained eosinophilic amorphous material stained with Congro red and anti-kappa light chain, and surrounded by inflammatory cells intermingled with plasma cells. Plasma cells in the adjacent amorphous material showed cytoplasmic staining with anti-kappa. Polymerase chain reaction revealed a discrete amplified band of apparently uniform size with background smear. CONCLUSIONS: Primary AL type localised amyloidosis involves local accumulation of monoclonal plasma cells and their secreted products, as in nodular cutaneous amyloidosis. Localised AL type nodular amyloidosis is a separate entity in amyloidosis. 相似文献

We describe a young Japanese woman who was diagnosed with Crohn's disease affecting the ileum, transverse colon, and rectum, as confirmed by barium studies, colonoscopy, and histopathological examination. Her father and sister also had Crohn's disease. After a 4-yr course of sulfasalazine and elemental diet therapy, she was readmitted for perianal abscess associated with the presence of pancytopenia, microhematuria with granular cast, hypocomplementemia, and high titers of autoimmune antibodies (anti-ANA and anti-dsDNA antibodies). Based on these features, a diagnosis of systemic lupus erythematosus (SLE) was made. Despite the rarity of such combination (Crohn's disease with SLE), patients with Crohn's disease who develop such clinical findings might need evaluation for SLE. 相似文献

Objective Classic Hodgkin lymphoma (CHL) has been regarded as a curable disease when treated appropriately, especially in younger patients, and ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) has been regarded as the standard regimen. However, a relatively poor prognosis has been reported in older patients with CHL, and the efficacy and tolerability of the ABVD regimen has not been fully elucidated. We retrospectively investigated the outcomes in patients with CHL treated with ABVD at our institute. Methods Twenty-five patients were evaluated; 14 were ≤60 years of age, and 11 were >60 years of age (older group). Results The ABVD doses were reduced in all patients in the older group; the median average relative dose intensity was 0.58. In the older group, the 5-year overall survival (OS) and median OS were 100% and not reached, respectively, for patients with early-stage CHL and 66.7% and not reached, respectively, for those with advanced-stage CHL. No patients died of CHL, and only one treatment-related death was observed in the older group. Conclusion ABVD with dose attenuation may represent a feasible and effective strategy for the treatment of older patients with CHL in clinical practice, particularly in those with early-stage disease, although the optimal degree of attenuation remains unclear. 相似文献

BACKGROUND/AIMS: Quality of life can be adversely affected in many patients who suffer phonation disorders such as hoarseness and dysphonia following esophagectomy. The present study investigated postoperative phonation disorders in 15 patients who underwent esophagectomy for esophageal cancer. METHODOLOGY: None of the patients had signs of hoarseness before or after surgery. Aerodynamic testing to assess phonatory function testing and laryngoscopy for observing laryngeal movements were performed before and after surgery. As a control, the same tests were conducted in 20 patients treated for gastric cancer by gastrectomy. RESULTS: For esophagectomy patients, mean postoperative flow rate was significantly increased and maximum postoperative phonation time was significantly decreased after operation. Laryngoscopy confirmed postoperative paralysis of left laryngeal movements and excessive adduction of the right, unaffected vocal cord during phonation in 8 of 15 esophagectomy patients, although hoarseness was not reported by any patient. No significant changes were observed for mean postoperative flow rate or maximum postoperative phonation time following surgery in gastrectomy patients. CONCLUSIONS: Surgical procedures in the vicinity of the recurrent laryngeal nerve appear to be the cause of postoperative phonation disorders in patients undergoing esophagectomy for esophageal cancer, and these disorders can occur in the absence of symptoms such as hoarseness and dysphonia. 相似文献

Purpose
Nephron sparing surgery is an effective surgical option in patients with renal cell carcinoma. Laparoscopic partial nephrectomy involves clamping and unclamping techniques of the renal vasculature. This study compared the postoperative renal function of partial nephrectomy using an estimation of the glomerular filtration rate (eGFR) for a Japanese population in 3 procedures; open partial nephrectomy in cold ischemia (OPN), laparoscopic partial nephrectomy in warm ischemia (LPN), and microwave coagulation using laparoscopic partial nephrectomy without ischemia (MLPN).Materials and Methods
A total of 57 patients underwent partial nephrectomy in Yokohama City University Hospital from July 2002 to July 2008. 18 of these patients underwent OPN, 17 patients received MLPN, and 22 patients had LPN. The renal function evaluation included eGFR, as recommended by The Japanese Society of Nephrology.Results
There was no significant difference between the 3 groups in the reduction of eGFR. eGFR loss in the OPN group was significantly higher in patients that experienced over 20 minutes of ischemia time. eGFR loss in LPN group was significantly higher in patients that experienced over 30 minutes of ischemia time.Conclusion
This study showed that all 3 procedures for small renal tumor resection were safe and effective for preserving postoperative renal function.Key Words: eGFR, Partial nephrectomy, Renal function, Laparoscopic partial nephrectomy 相似文献9.

A 58-year-old Japanese man was admitted complaining of abdominal pain. An abdominal computed tomography examination demonstrated
a tumor in the head of the pancreas and multiple calcifications. A laparotomy was performed and the tumor was removed by Whipple's
operation. Histologically, the neoplasm that invaded the duodenal wall and the papilla of Vater was composed of nests of malignant
squamous cells with intercellular bridges and showed the formation of keratinized pearls with a small area of concurrently
neoplastic glandular and squamous elements. On the basis of these features, the diagnosis of adenosquamous carcinoma of the
pancreas was made. The patient died 18 months after the operation. The neoplastic behavior of this rare primary pancreatic
carcinoma is similar to that of duct cell carcinoma as well as pure squamous cell carcinoma of the pancreas. As the pancreas
can be the target of metastases of squamous carcinomas from other organs it is wise to be aware of this rare entity. 相似文献
