The cumulative 7 d incidence of colonic perforation in this cohort was 0.06%. Advanced age and female gender were significantly more likely to have perforation. Increasing albumin and BMI resulted in decreased risk of colonic perforation. Having a colonoscopy indication of abdominal pain or Crohn's disease resulted in a higher risk of colonic perforation. Colonoscopies performed in inpatients and particularly the ICU setting had substantially greater odds of perforation. Biopsy and polypectomy did not increase the risk of perforation and only three perforations occurred with screening colonoscopy.
IntroductionPrimary hepatic lymphoma is an unusual form of non-Hodgkin's lymphoma that usually presents with constitutional symptoms, hepatomegaly and signs of cholestatic jaundice. Diffuse hepatic infiltration is uncommon and presentation with acute hepatic failure even more rare. The presence of markedly elevated ferritin levels can complicate the evaluation process and suggest alternative diagnoses.We present the case of a middle-aged woman exhibiting pancytopenia, hyperferritinemia and rapidly deteriorating to develop acute hepatic failure. Her initial clinical picture led to a working diagnosis of adult onset Still's disease with probable hemophagocytic syndrome before her worsening liver function necessitated a percutaneous liver biopsy and establishment of the final diagnosis of primary hepatic lymphoma.ConclusionPrimary hepatic lymphoma is an uncommon malignancy and its manifestation as progressive hepatitis or acute fulminant hepatic failure can be difficult to diagnose. The presence of constitutional symptoms, pancytopenia and high ferritin levels can complicate the evaluation process. A liver biopsy early in the course of liver dysfunction may establish the diagnosis without a higher risk of bleeding complications seen once liver failure sets in.
Between April 1980 and December 1985 a prospective controlled and randomized multicenter study of 124 assessable patients with stage I and II epithelial ovarian carcinomas was carried out. The aims of this study were first to verify the value of adjuvant irradiation therapy or combined chemo-irradiation therapy, and second to evaluate the importance of different prognostic factors such as age, histology, tumor grading, and tumor stage. Patients with well-differentiated stage IA tumors did not receive any therapy; patients with undifferentiated stage IA tumors were randomized to "no therapy" or irradiation therapy; patients with stage IB, IIA, and IIB tumors were treated by either irradiation or a combined chemo-irradiation therapy consisting of Adriamycin/Cyclophosphamide. In patients with stage IC and IIC ovarian carcinomas a combined irradiation-polychemotherapy was instituted, consisting either of Adriamycin/Cyclophosphamide or of Adriamycin/Cisplatin. Because of the low number of patients and the relatively good prognosis no definite evaluation of the individual therapeutic modalities could be done. An analysis of all patients showed that differentiation between stage I and stage II ovarian carcinomas is the single most important prognostic factor. After a mean observation time of 42 months (8-71 months) for stage I tumors a 91% probability of three-year survival was attained, in comparison with 57% for stage II tumors. It has not been definitely established that there is a need for adjuvant therapy for stage I tumors and this should be confirmed by further studies. Because of the unfavorable prognosis for patients with stage II ovarian cancer, these patients should be given the same polychemotherapy, including Cisplatin, as patients with advanced ovarian carcinomas.
Aim of this prospective study was to examine the value of the "Immunosuppressive Acidic Protein" (IAP) as a tumour marker for epithelial ovarian carcinomas and to compare the results with these of the established tumour marker CA-125. In 75 patients with malignant ovarian tumours and in 36 patients with benign ovarian tumours and in 68 healthy women the serum IAP and CA-125 values were determined. In dependence of the threshold for the IAP (500 or 800 microgram/ml) a pronounced lower specificity (70.2% or 97.1%) or sensitivity (88% or 40%) could be achieved in comparison with the CA-125 (95.2% specificity and 81.3% sensitivity). In only 4% of all ovarian carcinomas the CA-125 was false negative and the IAP right positive. Whereas the serum CA-125 level correlated in 86.9% of the patients with the clinical course of disease, the serum IAP level correlated only in 43.3% of the patients with their clinical course of disease. We therefore concluded, that the IAP is less suitable as a tumour marker in ovarian carcinomas than the CA-125 and even the combination of both markers is only beneficial for a very small number of patients.
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.
