In this report, we aim to present our algorithm and results of patients with congenital cardiac disorders who underwent surgical or interventional procedures during the peak phase of the pandemics in our country.
Patients and methods:
The first COVID-19 case was diagnosed in Turkey on 11 March, 2020, and the peak phase seemed to end by the end of April. All the patients whom were referred, treated, or previously operated but still at the hospital during the peak phase of COVID-19 pandemics in the country were included into this retrospective study. Patient’s diagnosis, interventions, adverse events, and early post-procedural courses were studied.
Thirty-one patients with various diagnoses of congenital cardiovascular disorders were retrospectively reviewed. Ages of the patients ranged between 2 days and 16 years. Seventeen cases were males and 14 cases were females. Elective cases were postponed. Priority was given to interventional procedures, and five cases were treated percutaneously. Palliative procedures were preferred in patients whom presumably would require long hospital stay. Corrective procedures were not hesitated in prioritised stable patients. Mortality occurred in one patient. Eight patients out of 151 ICU admissions were diagnosed with COVID-19, and they were transferred to COVID-19 ICU immediately. Three nurses whom also took care of the paediatric cases became infected with SARS-CoV-2; however, the children did not catch the disease.
Mandatory and emergent congenital cardiac percutaneous and surgical procedures may be performed with similar postoperative risks as there are no pandemics with meticulous care and preventive measures.
To evaluate the impact of leg position on the dose distribution during intracavitary brachytherapy for cervical cancer.
Patients and methods
This prospective study was performed on 11 women with cervical cancer who underwent intracavitary brachytherapy. After insertion of the brachytherapy applicator, two sets of computed tomography slices were taken including pelvis, one with straight leg and one with leg flexion position with knee support. The dose (7 Gy) was prescribed to point A. The radiotherapy plan was run on the Plato Planning Software System V14·1 to get the dose distributions. Also, rectum and bladder doses were measured for both leg positions during the treatment. The doses and volumes of organs were compared via the Wilcoxon signed-rank test by using Statistical Package for the Social Sciences 11·5 statistical software.
No significant difference regarding the dose distributions and volumes of target, sigmoid and bladder due to leg position was observed, either on 3D planning or on in vivo dose measurements. However, there were significant differences for 25 and 50% isodose coverage of rectum in favour of straight leg position (p=0·026). There were no significant differences regarding maximum doses in any critical organ.
Difference in leg position caused only a small change in rectum dose distribution and did not cause any other change in either dose distributions or in vivo measured doses of both target and critical organs during cervical brachytherapy. Straight leg position appears better with regard to rectum dose.
