A Swiss neighbourhood index of socioeconomic position: development and association with mortality

Area-based measures of socioeconomic position (SEP) suitable for epidemiological research are lacking in Switzerland. The authors developed the Swiss neighbourhood index of SEP (Swiss-SEP).

The Position of Russian Provinical Officialdom in the Middle of the 19th Century: Law and Life

The study considered the discrepancy between the official status and real position of Russian provincial officialdom in the middle of the 19th century. The law was not entirely coherent in all aspects of the officials' life and activity, with ordinary deviations from the law being adopted in practice and accepted, albeit not openly, by the public and sometimes even by the authorities. The main law determining the rights and duties of governors was never followed to the letter and in reality governors' activities were determined by the common (unwritten) law existing in the governmental sphere. The volume and nature of the governors' rights depended on a range of factors, with specific regional features and the governor's personal qualities having a particular significance. The standard of living of government clerks was much higher than their official salary would permit and Matkhanova studied the most widespread cases of abuse, identifying those positions in the administration which offered the most opportunities for such abuses. At the start of the period and on the eve of the reforms public opinion towards the bribery of officials underwent a change. From the late 1850s onwards, there appeared among provincial officials a group of young well-educated clerks with liberal ideas and a new system of moral values which did not allow them to accept bribes or infringe the law in any way. There was also a non-official hierarchy side by side with the legally existing one. A significant role in governing the region, and one which has been underestimated by historians, was played by the head of the governor's office, but the reforms of the 1860s contributed to changing this state of affairs.

Sonographic visualization and ultrasound-guided block of the third occipital nerve: prospective for a new method to diagnose C2-C3 zygapophysial joint pain

BACKGROUND: Chronic neck pain after whiplash injury is caused by cervical zygapophysial joints in 50% of patients. Diagnostic blocks of nerves supplying the joints are performed using fluoroscopy. The authors' hypothesis was that the third occipital nerve can be visualized and blocked with use of an ultrasound-guided technique. METHODS: In 14 volunteers, the authors placed a needle ultrasound-guided to the third occipital nerve on both sides of the neck. They punctured caudal and perpendicular to the 14-MHz transducer. In 11 volunteers, 0.9 ml of either local anesthetic or normal saline was applied in a randomized, double-blind, crossover manner. Anesthesia was controlled in the corresponding skin area by pinprick and cold testing. The position of the needle was controlled by fluoroscopy. RESULTS: The third occipital nerve could be visualized in all subjects and showed a median diameter of 2.0 mm. Anesthesia was missing after local anesthetic in only one case. There was neither anesthesia nor hyposensitivity after any of the saline injections. The C2-C3 joint, in a transversal plane visualized as a convex density, was identified correctly by ultrasound in 27 of 28 cases, and 23 needles were placed correctly into the target zone. CONCLUSIONS: The third occipital nerve can be visualized and blocked with use of an ultrasound-guided technique. The needles were positioned accurately in 82% of cases as confirmed by fluoroscopy; the nerve was blocked in 90% of cases. Because ultrasound is the only available technique today to visualize this nerve, it seems to be a promising new method for block guidance instead of fluoroscopy.
