This report describes a paradoxical inflammatory reaction to Seprafilm caused by extensive adhesion formation early in the postoperative period. A female patient had development of small bowel obstruction immediately after an uneventful low anterior resection for rectal carcinoma with placement of Seprafilm. The obstruction did not improve with nonoperative therapy. At laparotomy, extensive adhesions necessitating bowel resection and ileostomy were noted. Pathology results showed a giant cell foreign body reaction to Seprafilm. A literature search yielded only two other instances of adverse reactions to Seprafilm. The information provided by this and other atypical reports suggests that further studies aimed at identifying the incidence and pathophysiological mechanisms for such paradoxical reactions are needed.
Cystic echinococcosis is observed worldwide. Traditional management includes an invasive surgical approach with adjunctive chemotherapy. It has been suggested that observation alone may be appropriate in asymptomatic individuals with stable cysts. A case involving a 38-year-old Peruvian man with an asymptomatic bronchogenic cyst (suspected to be due to echinococcus, but never definitely diagnosed) is presented. The cyst was first noted in 1998, and was followed for 10 years during which time he remained asymptomatic with minimal radiographic change. One year later, in 2009, he presented with acute rupture of the cyst causing empyema. The patient required thoracotomy, decortication and resection of the ruptured cyst. Final pathology showed Echinococcus organisms. The patient responded well to treatment with albendazole and praziquantel, and became completely asymptomatic within six months. The present case demonstrates that echinococcal cysts may be at risk of spontaneous rupture, even after many years of clinical stability, thus supporting the case for resection of asymptomatic cysts suspected of being echinococcal at the time of diagnosis. In addition, the case illustrates that medical therapy with albendazole and praziquantel, in conjunction with surgical drainage, can be successful in the treatment of echinococcal empyema.
Context.—Bone marrow aspirates as well as bone marrow trephine biopsies are frequently performed to assess whether there is marrow involvement by a malignancy. Numerous reports differ in the relative value of these 2 procedures and fail to provide concise guidelines that can help choose the appropriate technique in this clinical situation.
Objective.—To compare the relative value of aspirates and trephine biopsies in the diagnosis of solid tumor metastasis and Hodgkin lymphoma. In addition, we correlate our findings with those of the literature to provide a concise practice guideline.
Design.—Sixty-six cases showing bone marrow involvement by solid tumor and Hodgkin lymphoma in bone marrow aspirates, bone marrow trephine biopsies, or both were included in the study. The diagnosis and findings made on aspirates were compared with those made on trephine biopsies in each case.
Results.—In those cases where both aspirate and trephine biopsy were available for evaluation, there was a 22% positive correlation in the findings on aspirates and trephine biopsies. The correlation between aspirates and trephine biopsies was highest in cases of small cell carcinoma of the lung (3/11, or 36.3%) followed by breast carcinoma (7/20, or 35%), prostate carcinoma (1/9, or 11.1%), and Hodgkin lymphoma (1/20, or 5%). Two of 5 cases from the miscellaneous category demonstrated simultaneous involvement of aspirate and trephine biopsy by a gastric carcinoma as well as an adrenal gland carcinoma.
Conclusions.—Bone marrow aspirate and bone marrow trephine biopsy should both be performed in patients with proven or suspected malignancies where staging may affect management. However, bone marrow aspirate has only a minimal role, if any, in detecting bone marrow involvement by Hodgkin lymphoma. In cases of breast carcinoma, small cell carcinoma of lung, and prostate carcinoma, aspirate evaluation may confirm trephine biopsy results or, more rarely, provide the sole confirmation of the malignancy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
