RESUMO
Background: Worldwide, diffuse large B-cell lymphoma (DLBCL) represents the most common subtype of non-Hodgkin lymphoma (NHL), accounting for 30%-40% of all newly diagnosed cases. The response rate to currently available chemotherapy in DLBCL is much unsatisfactory. Dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide and doxorubicin (DA-EPOCH) was developed in an effort to improve outcome in patients with diffuse large B-cell lymphoma. To assess the efficacy and safety of DA-EPOCH chemotherapy in patients with diffuse large B-cell lymphomas.Material & Methods:This quasi experimental study was conducted in the department of Hematology, DMCH, from January 2016 to December 2017. 20 patients with diffuse large B-cell lymphomas were treated with etoposide, vincristine, and doxorubicin for 96 hours with bolus doses of cyclophosphamide and oral prednisone (DA-EPOCH chemotherapy). The doses of etoposide, doxorubicin and cyclophosphamide were adjusted to achieve a nadir absolute neutrophil count below 0.5× 109/L. Cycles were repeated after 21 days. After 3rd and 6th cycle patients were evaluated for interim analysis and response evaluation respectively. Evaluation was done in aspect of clinical parameter (lymph node size, physical complaint), laboratory parameter (CBC) and radiological imaging (CT scan of chest and abdomen). The median age of the patient was 46.5 years (range, 25-62 years); 20% were older than 50 years; and 25% were at high-intermediate risk according to International Prognostic Index (IPI) criteria. The statistical analyses were done by appropriate methods.Results:There was a complete response in 73.7% of patients and partial response 10.5% of patients, which were evidenced by significant reduction of size of the lymph nodes after chemotherapy. The mean Serum LDH was also significantly lower after chemotherapy in comparison to before chemotherapy in those patients who achieved complete or partial response. Moreover, size of the liver and spleen were significantly lower after chemotherapy in response group patients who had either hepatomegaly or splenomegaly or both. Doses were escalated in 12.50% cycles and toxicity levels were acceptable.Conclusion:DA-EPOCH chemotherapy is an effective regimen for treatment of diffuse large B-cell lymphoma patients.
RESUMO
Background: Repeated cesarean section involves various complication and one of the most common is adhesion. Some studies suggest that by closing the parietal peritoneum layer, the adhesion rate after surgery can might be decreased. The aim of this study was to assess the necessity of parietal peritoneum layer closure to prevent severe adhesion in repeat caesarean section.Material & Methods:This cross-sectional study was conducted in department of obstetrics and gynaecology, Care Medical College Hospital, Dhaka, Bangladesh from 2020 to 2022. Total 100 pregnant women were included in this study. These patients were divided into two groups where each groups contained 50 pregnant women. Here the two groups are parietal peritoneum layer closure and of parietal peritoneum layer non-closure.Results:Mean age of the pregnant women was 28.6 years (SD±4.50 years) in parietal peritoneum layer closure group and 30.4 years (SD±4.91 years) in parietal peritoneum layer non-closure group. 58% pregnant women in parietal peritoneum layer closure group and 60% in parietal peritoneum layer non-closure group had short inter delivery interval. The commonest comorbidity was hypertension in both groups (22% and 20%). Mean operating time was 35.6 minutes (SD±8.93 minutes) in parietal peritoneum layer closure group and 32.4 minutes (SD±9.50 minutes) in parietal peritoneum layer non-closure group. Mean hospital stay was 4.2 days (SD±1.01 days) in parietal peritoneum layer closure group and 4.8 days (SD±1.02 days) in parietal peritoneum layer non-closure group. The adhesion rate was 12% in parietal peritoneum layer closure group and 28% in parietal peritoneum layer non-closure group. The parietal peritoneum layer closure group had adhesion commonly in fascia to uterus (4%) and omentum to uterus (4%). The parietal peritoneum layer non-closure group had adhesion commonly in omentum to fascia (12%).Conclusion:Closure of the parietal peritoneum layer in caesarean section resulted in less adhesion formation. Thus, it is necessity to perform parietal peritoneum layer closure to prevent severe adhesion in repeat caesarean section.
