Q: Question: Do medical students ' clinical skills match their teachers ' expectations : survey at Zagreb University School of Medicine , Croatia?
Answer: Students' self-assessed level of clinical skills was lower than that expected by their teachers. Education during clinical rotations is not focused on acquiring clinical skills, and additional clinical skills' training has a positive influence on students' self-assessed level of clinical skills. There was no consensus among teachers on the required level of students' clinical skills.

Q: Question: Do an update in the palliative management of malignant dysphagia?
Answer: Palliative treatment for oesophageal cancer should be individualized and relate to tumour stage, size and location, the patient's medical condition and his/her personal wishes.

A multi-disciplinary approach is vital in patients with advanced oesophageal cancer.

Q: Question: Does photobiont selectivity lead to ecological tolerance and evolutionary divergence in a polymorphic complex of lichenized fungi?
Answer: Low selectivity apparently allows widespread lichen-forming fungi to establish successful symbioses with locally adapted photobionts in a broader range of habitats. This flexibility might correlate with both lower phylogenetic resolution and evolutionary divergence in species complexes of crustose lichen-forming fungi.

A:
yes
