Evaluation of knowledge and attitudes of radiology department workers about artificial intelligence

Aim: The objective of this study was to investigate the knowledge and attitudes of radiology department workers through a survey.

Material and Methods: In this study, the opinions and attitudes of physicians, residents and technicians working in radiology departments of various hospitals and medical students in our university about AI were collected through a survey conducted between 01/07/2020 and 12/08/2020 and analyzed through a survey.

Results: The response rate of the survey was 25.3%; 47.1% of the participants reported that they have enough knowledge about AI applications in general, while only 25% stated that they hadsufficient knowledge about AI applications in radiology. Among all participants, 35.3% thought that AI applications would negatively affect the profession of radiologists, while 30.3% thought that these applications would have positive impacts;  51.9% of the participants think that AI applications will save time for radiologists. The rate of participants who were concerned about the advances in AI was 16.1%. 

Discussion: Further similar studies should be conducted on this issue in order to obtain more detailed information and contribute to the literature. We believe that our results will be guiding for further comprehensive studies on the opinions of radiology department workers about the use of AI in the field of radiology.

The effect of positive end-expiratory pressure on optic nerve diameter in patients undergoing craniotomy operation

Aim: In this study, we aimed to investigate the effect of PEEP on changes in intracranial pressure with the guidance of ultrasonographic measurement of the optic nerve, in patients who underwent craniotomy operation in the supine position.

Material and Methods: A total of 60 patients evaluated as ASA I-II and who were scheduled for craniotomy operation in the supine position under elective conditions were included in the study. Following routine monitorization of anesthesia induction, patients were provided with 1 mcg/kg iv fentanyl, 3 mg/kg iv thiopental sodium, 0.6 mg/kg iv rocuronium. Anesthesia maintenance was then provided with 2% sevoflurane and remifentanil (0,05-2 mcg/kg/min) infusion to keep BIS between 40 and 65. Patients in Group I received a 5 cmH2O PEEP, while those in Group II received 0 cmH2O PEEP. Patients’ HR, SAP, DAP, MAP, end-tidal carbon dioxide (ETCO2), SpO2, Ppeak, Pmean, minute volume, Tv expiratory, ONSD values were measured at following time-points: T0-before anesthesia induction, T1-after the dura is opened, T2-immediately before the dura is closed, T3-before extubation.

Results: There was no statistical difference in hemodynamic parameters ( SAP, DAP, MAP ) between the two groups (p>0.05). ONSD was similar between both groups at all time points except for T2 results . The mean ONSD at T2 was significantly higher in Group I (p=0.04). Ppeak and Pmean were significantly higher in Group I at all time points (p<0.05).

Discussion: We investigated the effect of PEEP on the optic nerve sheath diameter and its indirect effect on intracranial pressure; we revealed that two different PEEP levels did not create a difference.

Is sternum fracture a concerning clinical situation?

Aim: In this study, it was aimed to investigate the demographic characteristics of the patients diagnosed with sternum fracture (SF) admitted to our hospital in the last year, the treatments applied, and the etiological factors causing SF.

Material and Methods: Fifty-six patients diagnosed with SF as a result of blunt trauma were retrospectively analyzed. Only cases with blunt trauma and SF were included in the study.

Results: A total of 56 cases, 34 males (60.8%) and 22 females (39.2%), who had thoracic trauma and SF together were included in our study.  In 33 (58.8%) cases, a motor vehicle accident was the mechanism with the highest rate of trauma. Rib fracture was most commonly accompanied by SFs in 28 cases (50%). The most common extra-thoracic additional organ injury was extremity fracture at various levels, which was confirmed in 13 cases (23.2%). Twelve (21%) patients with isolated SF were kept under observation in the emergency department and provided with pain relief. These patients were recommended to come for control 5 days later and were discharged. The number of cases we applied medical treatment was 50 (89.2%). There were no deaths directly related to SF.

Discussion: Sternum fracture due to trauma indicates that the trauma is severe. Cases must be evaluated in terms of additional organ injury. Mortality occurs especially in patients with multiple trauma and for reasons other than thoracic. Patients with isolated non-complicated, non-displaced SF do not need hospitalization if there are no additional organ injuries or uncontrolled pain.
