This study demonstrates that airway management using the PLMA is safe and effective in a general practice setting. The results support the assumption that a correctly positioned PLMA can protect from pulmonary aspiration of regurgitate gastric fluid. The data also support use of the PLMA for the management of the difficult airway.

This survey demonstrates that the PLMA can be used effectively in infants, children and adolescents in the routine university clinical practice setting. However, this study does not confirm the extremely high success and low complication rates reported in controlled studies. The results support the assumption that with the PLMA regurgitated gastric fluid can be drained away from the larynx through the drain tube.

Background Women make up a significant proportion of workforce in healthcare. However, they remain underrepresented in leadership positions relating to healthcare for a multitude of reasons: balancing personal and work duties, favoritism toward men, lack of support from colleagues and mentors, as well as other factors. This study aims to recognize the contribution made by women in the Bahraini healthcare sector by determining the gender distribution in Bahrain’s medical schools, government hospitals, Ministry of Health, and National Health Regulatory Authority. Methods Data were collected from the Bahraini Ministry of Health, National Health Regulatory Authority, Salmaniya Medical Complex, King Hamad University Hospital, Bahrain Defence Force Royal Medical Services, the College of Medicine and Medical Sciences in the Arabian Gulf University, and the Royal College of Surgeons in Ireland-Bahrain. Only physicians who held a Bachelor of Medicine and Surgery and a valid license to practice from NHRA were eligible to participate. Descriptive statistics were used to derive the frequencies and percentages of physicians with the following leadership positions: (1) top administrative positions (e.g., Chief executive officer); (2) heads of departments; (3) heads of committees; and (4) academic positions (e.g., Professor). Data were also collected from the two medical schools in Bahrain to see the trend in female enrollment into medical schools since 2004. Results The results of the study indicated that leadership positions were mostly held by males in Bahrain (59.4% vs. 40.6%). However, Bahraini males and females equally dominated academic positions. Male physicians also dominated surgical specialties; however, female Bahraini physicians slightly surpassed male Bahraini physicians at the specialist and consultant levels (female to male: 11.9% vs. 10.4% and 33.2% vs. 30.4%, respectively). Furthermore, more females were reported to have general licenses. A trend analysis since 2004 showed that female medical students’ representation was higher than males over the years. Conclusions This study highlights the increasing trend of women’s participation and contribution to medicine in Bahrain. The data indicated continued growth in the number of female medical students and physicians. As such, it is likely that females will have a bigger impact on healthcare in the future with potential to hold more leadership positions in Bahrain.

93 Background: TACE with irinotecan-loaded drug-eluting beads has shown activity in colorectal liver metastases. Among the factors potentially interfering with its effectiveness is a hypothetical neo-angiogenic reaction due to ischemia. Methods: Patients with predominant liver metastases from CRC which were refractory to chemotherapy and documented tumor progression during or shortly after the last chemotherapy, were prospectively treated with irinotecan-loaded drug-eluting beads with a size of 100-300 µm. Therapy was applied by a temporary catheter placed in the liver arteries. Usually each lobe of the liver was according to the recommended DEBIRI treatment algorithm. Each treatment of one liver lobe was performed with 1 vial of the 100-300 µm DC-Beads loaded with 100 mg irinotecan. Blood samples to measure the VEGF serum levels were taken before TACE and at days 7, 14, and 21 after first treatment. Results: Complete blood samples were taken from 15 patients from 2/11 to 2/12. 60% of patients had an increase of the VEGF-A-Level with a median of 107 %, 40% of patients had a decrease of the VEGF-A-Level with a median of – 39% respectively. The relative decrease of the VEGF-A-Levels depends on a prior liver resection (p=0.05), and a significant decrease was found in patients with a prior bevacizumab therapy (p=0.025). A trend to an increase in VEGF-A-Levels was detected in patients with a low count of liver metastases (p=0.087). Conclusions: These findings show different behavior of the VEGF-A-levels after DEBIRI-TACE, suggesting that the occlusion of blood vessels and subsequent ischemia induces neo-angiogenesis due to these growth factors in a subset of 60% of the patients treated with a DEBIRI-TACE. We found a trend for a lower count of liver metastases, prior liver resection and a prior bevacizumab-therapy, respectively influencing the VEGF-A-Level-changes. The trend toward a decrease in patients with a prior bevacizumab therapy may be due to a neoangiogenesis-pathway other than VEGF-mediated. These first results could implicate that antiangiogenic drugs might be effective as an additive therapy to chemoembolization in a subset of patients, e.g., those with no prior bevacizumab therapy.
