The effects of gemeprost on the second trimester fetus
Objective To determine whether the use of gemeprost is associated with histological changes in the second trimester fetus.
Setting Histopathology department of a university hospital.
Design Retrospective comparison of histological features in fetuses aborted following maternal administration of gemeprost, with those in fetuses after spontaneous miscarriage.
Outcome measures Degree of tissue fragmentation; other histological abnormalities.
Results Significantly greater fragmentation of the liver was found in fetuses exposed to gemeprost (P= 0–046). Nonsignificant effects were found for brain (P= 0.082) and heart (P= 0.183), and no effect was seen on the kidney, adrenal and lung. No other significant histological differences were found between the two groups.
Conclusions This study is the first to document an effect of gemeprost on the fetus, but confirmation is required in further studies. Other implications are discussed
Fine needle aspiration (FNA) cytology of the breast: The influence of unsatisfactory samples on patient management
FNA continues to play an important role in the management of patients with breast lesions. However, the reliability and efficiency of the FNA service depends heavily on the quality of the specimens. We have audited the rate of "inadequate FNAs' at intervals over the last 5 years and related our findings to the clinical expertise of the aspirator. We have also correlated the rate of inadequate FNAs with the percentage of patients who had an FNA preceding a definitive diagnosis of cancer. We report trends in the rate of inadequate samples, and subsequent diagnosis of cancer, over a 5-year period. The percentage of breast FNA samples reported as inadequate was 46.8% in 1988-89, falling to 20% in 1991-92 with the introduction of an FNA clinic, and rising to 30.6% in 1993. The rates of cancer following inadequate FNA were 15.7%, 16.1% and 4.2%, respectively, and the percentage of patients with cancer having a preceding inadequate FNA were 37.5%, 13.2% and 7.1%. Possible explanations for the apparent paradox between increasing numbers of inadequate FNA specimens and a falling breast cancer rate are discussed
Effect of Recipient Sensitization (Peak PRA) on Graft Outcome in Haploidentical Living Related Kidney Transplants
OBJECTIVE: To evaluate the influence of pre-transplant recipient sensitization on the outcome of 1-haploidentical live related donor (LRD) kidney transplants.
METHOD: We reviewed 141 consecutive cyclosporine-treated adult haploidentical first transplants for which panel reactive antibody (PRA) levels were available. Patients were divided into three groups according to their peak PRA levels: group I, PRA = 0 (n = 97); group II, PRA = 1-50% (n = 24); and group III, PRA = 51-100% (n = 20).
RESULTS: Differences in PRA were associated with significant differences in short- and longer-term graft survival, unrelated to patient survival. Graft survival at 1, 3, and 5 yr was only 74, 40, and 27% in group III, compared to 92, 87, and 52% in group II, and 96, 91, and 85% in group I (p \u3c 0.001). Increasing PRA was associated with shorter time-to-graft failure. In group III, 20% lost their transplant from acute rejection in the first 6 months, versus 4% in group II and 3% in group I (p \u3c 0.01). Graft survival in group II diverged from that of group I only after 3 yr, due to an increase in loss from chronic rejection. Hospitalization was longer in group III, in association with a significantly higher incidence of acute rejection during the first 3 months after transplantation (p \u3c 0.02). Serum creatinine was higher in sensitized than nonsensitized patients at all time points.
CONCLUSIONS: Sensitization has a significant negative impact on the outcome of haploidentical LRD kidney transplants. Sensitized potential recipients and their potential donors should be aware of this in arriving at informed decision-making for transplantation. These patients may benefit from more sensitive cross-match testing, more intense or more novel immunosuppression, or immunomodulation to modify their immune responsiveness
