Although learning is generally perceived as a way to improve employees' current job performance, so far, no research has been conducted to explore the possible relationships between formal and informal learning, on the one hand, and employability, on the other. Though contemporary views stress the importance of the job as a powerful learning site, considerable research evidence underpinning these views is lacking. This paper goes into the impact of formal and informal learning upon employability. The influence of employee characteristics and organizational factors is also taken into account. An e-questionnaire was used to collect data among 215 Dutch non-academic university staff members. Our findings emphasize the necessity of Human Resource Development strategies that encompass a mix of formal and informal learning opportunities. In particular, participation in networks appears to be an important predictor for employability. With the outcomes of this study, we aim to contribute to the further development of theoretical insights regarding employability enhancement through learning possi-

The safe and successful performance of a lumbar puncture demands a working and specific knowledge of anatomy. Misunderstanding of anatomy may result in failure or complications. This review attempts to aid understanding of the anatomical framework, pitfalls, and complications of lumbar puncture. It includes special reference to 3D relationships, functional and imaging anatomy, and normal variation. Lumbar puncture is carried out for diagnostic and therapeutic purposes. Epidural and spinal anesthesia, for example, are common in obstetric practice and involve the same technique as diagnostic lumbar puncture except that the needle tip is placed in the epidural space in the former. The procedure is by no means innocuous and anatomical pitfalls include inability to find the correct entry site and lack of awareness of structures in relation to the advancing needle. Headache is the most common complication and it is important to avoid traumatic and dry taps, herniation syndromes, and injury to the conus medullaris. With a thorough knowledge of the contraindications, regional anatomy and rationale of the technique, and adequate prior skills practice, a lumbar puncture can be carried out safely and successfully.

The safe and successful performance of a cricothyroidotomy demands a working and yet specific knowledge of anatomy. An ignorance or misunderstanding of anatomy may result in failure or complications. The Educational Affairs Committee of the American Association of Clinical Anatomists has highlighted the importance of clinical anatomy for several invasive procedures. This review is building on their work and contribute further to the understanding of the anatomical framework, particularly the pitfalls and complications related to performing a cricothyroidotomy.

Results of this study indicate that the dimensions of the cricothyroid membrane are too small for passing a tracheal tube as the dimensions of the tube exceeds that of the cricothyroid membrane. This could fracture the cartilages of the larynx. The performance of a surgical cricothyroidotomy with passing of a tracheal tube is therefore strongly discouraged in neonatal patients.
