Little is known regarding the profiles of whole body donors in Muslim majority countries where donation is scarce. Therefore, this study aims to profile registered donors in Turkey by means of a survey. The explored data could be used to improve ongoing campaign efforts and ethical practices such as commemoration services. Registered donors of the donation programs at the two faculties of medicine of Istanbul University were compared with the national population and a cluster analysis was performed to reveal any concealed sub‐groups. Data from 188 respondents were analyzed. The majority of registered donors were married (42%), male (65.4%), aged over 50 years (76%), held a tertiary education degree (49.7%), and were irreligious (58.5%). Cluster analysis revealed two groups with significantly different educational levels, marital statuses, and religious choices. Regarding whether their bodies could be used for education or research, the majority (64.5%) of the respondents left the decision to the anatomy department. Similarly, 73.8% approved indefinite use of their organs, body parts and/or skeletons. The respondents were also willing to share their medical history (94.2%) and personal information (81.6%) if needed. Motivational themes for body donation including usefulness, impermanence, religion, awareness, and kinship were devised after a thematic analysis. Among the respondents, 56.5% were registered organ donors and 63.3% were frequent blood donors. The results of this study provide data that may help revising informed consent forms, developing and implementing thanksgiving ceremonies, and selecting additional targets for supporting body donation campaign activities such as organ and blood donation units.

Background/aim The aim of this cadaveric study was to investigate the erector spinae plane block (ESPB) in lumbar region and to elucidate the possible mechanisms of action of these injections in lumbar radicular pain by means of detecting expected dye dispersion to the neural structures. Materials and methods Ultrasound-guided lumbar ESPB was performed in three formaldehyde-embalmed human cadavers. For this purpose, a 10 mL of methylene blue was injected into the fascial space between the L4 transverse process and the erector spinae muscles. Then, the cadavers were dissected, the cephalocaudal and lateral spread of the dye was examined, and the involvement of the dorsal rami, dorsal root ganglia and ventral rami were analyzed. The distribution into the epidural space was also evaluated. Results The involvement of the dorsal rami was found to extend up to the T12 level and down to the L5 spinal nerves. Although dye dispersion was detected on the dorsal root ganglion in all specimens, it was found to be limited to one or two levels, unlike the dorsal rami. In half of the specimens, distribution to the ventral ramus and posterior epidural space was observed. Conclusion The lumbar ESPB is an interfascial block technique, which can be used to avoid complications, taking advantage of ultrasound. It can be preferred as an alternative to periradicular injection in patients with lumbar radicular pain. It seems to be useful for regional anesthesia, particularly with an increased injectate volume.

Summary: Comprehensive knowledge of nasal anatomy is essential for obtaining aesthetically and functionally pleasing results in rhinoplasty. In this study, the authors described the anatomy, histology, and clinical relevance of the interdomal region, keystone, and scroll complex. The current study examined these areas in 26 fresh cadaver heads. All cadavers were fresh, and no conservation or freezing processes were applied. All dissections were performed by the first author. It was determined that the structure that connected the middle crura in the interdomal region actually came together in the transverse plane and contained abundant capillaries within. It was observed that chondroblasts with high regenerative potential were present in the keystone area, and there was very tight attachment between periosteum and perichondrium. The scroll complex was found to be more flexible and thin and had fewer regenerative cells compared to the keystone region. With its unique anatomy and histology, the keystone acts as a transition area between the flexible and fixed units of the nose. The scroll complex should be taken into consideration during rhinoplasty because of its effects on fixation of the skin in the lateral supratip area and functional effects on internal and external nasal valves. The interdomal ligament, in contrast, acts as a transition between both middle crura rather than a real ligament.
