Conclusion: Our study demonstrates ALDH1 is significantly expressed in dysplatic lesions arising from IBD. ALDH1-expression in cancer stem cells suggest an important causative role in the progression to cancer in IBD. Although we found high sensitivity for dysplasia, the specificity was poor. In addition to neoplasia, ALDH1-expressing stem cells proliferate in response to chronic inflammation, accounting for the cases of inflammatory atypia with positive ALDHI1 expression.


Sarcoidosis Cannot Be Reliably Distinguished From Other Causes Of Hepatic Granulomas In A Liver Biopsy Alone, Phililp A. Grieshaber, Md, Whitney Jackson, Md, John L. Farber, Md Oct 2010

Sarcoidosis Cannot Be Reliably Distinguished From Other Causes Of Hepatic Granulomas In A Liver Biopsy Alone, Phililp A. Grieshaber, Md, Whitney Jackson, Md, John L. Farber, Md

Context:

Hepatic granulomas occur in a variety of circumstances. Sarcoidosis is a common cause with the liver following lymph nodes and the lung in frequency of involvement. The present study aimed to determine where granulomatous hepatisis caused by sarcoidosis can be distinguished in a liver biopsy from other etiologies.


The Added Value Of Molecular Testing In Small Pancreatic Cysts, Adam D. Toll, Md, Marluce Bibbo, Md Oct 2010

Background:

Cystic lesions of the pancreas (CLP) represent a relatively common pathologic entity affecting at least 1% of medical patients and represent a spectrum of lesions from inflammatory pseudocyststo malignant neoplasms. A significant percentage of these cysts are found incidentally during imaging work-up for unrelated conditions and require appropriate diagnostic testing to characterize the nature of the CLP. A multi-disciplinary approach to characterize CLP is currently used involving cytology, imaging, and cyst fluid analysis. The most recent international guidelines recommend resection of pancreatic mucinouscysts >3 cm, or smaller cysts with positive cytology, mural nodules, or symptoms.

Recent work utilized DNA …

Case Study:

A 26 year-old female (G3P1) had a D&E in March, 2010 for a blighted ovum. The diagnosis on the uterine contents at an outside institution was placental site trophoblastic tumor. No follow up care was obtained. Four months later (July, 2010), the patient presented to her OB-GYN stating that she had missed a period and had a positive home pregnancy test. An ultrasound examination failed to identify a fetus, and the patient was referred to TJUH.

At Jefferson an MRI showed a poorly defined uterine mass that extended into the myometrium. The slides from the original D&E were …


Loss Of Stromal Caveolin-1 Independently Predicts Poor Disease-Free Survival And Time To Recurrence In Patients With Prostate Cancer, M. Wagner, A. Dasgupta, F. Sotgia, R. B. West, M. P. Lisanti, A. K. Witkiewicz May 2010

Results:

Of the 167 patients originally included in the study, 43 were either lost to follow up or had insufficient clinical data for comparison. Of the remaining 124 cases, 32 showed loss of stromal Cav-1. Statistical analysis revealed no significant association between stromal Cav-1 loss and the usual markers of disease severity including Gleason grade, stage and presence of metastases. Kaplan-Meier curves showed a significant association between stromal Cav-1 loss and poor disease-free survival and time to recurrence (p<0.05), but no significant association with cancer-specific survival.

Transfusion-acquired babesiosis can be an asymptomatic or self-limited febrile hemolytic illness in a healthy host. A persistent, relapsing, and/or fulminant course with the development of life-threatening complications may be seen in immunocompromised or splenectomized patients. As in malaria, erythrocyte parasitemia is often associated with nonimmune hemolysis, and can be treated with erythrocytapheresis. Just as warm autoantibodies have been reported in malaria infection, the development of autoantibody-mediated immune hemolysis has been reported in babesiosis. We treated a previously healthy male with multiple injuries from a motor vehicle accident necessitating massive transfusion. Late in the hospitalization, his blood smear revealed Babesia microti, …
