There is significant evidence to show that many neurosurgical patients with hyponatremia, who were previously diagnosed with syndrome of inappropriate antidiuretic hormone secretion(SIADH), actually have cerebral salt wasting syndrome(CSWS). The critical difference between SIADH and CSWS is that CSWS involves renal salt loss leading to hyponatremia and volume loss, whereas SIADH is a euvolemic or hypervolemic condition. The primary treatment for CSWS is water and salt replacement. The mechanisms underlying CSWS are not understood but may involve ANP or other natriuretic factors and direct neural influence on renal function.

Objective To compare the application value and the clinical curative effect of longitudinal incision and tarsal sinus minimal-ly invasive approach in treatment of patients with intra-articular calcaneal fractures. Methods A retrospective statistical analysis was made by collecting and comparing the clinical data of 67 patients with intra-articular calcaneal fractures from March 2008 to March 2012,and they were divided into the longitudinal incision minimally invasive approach group ( ZW group,36 patients,37 feet) and the tarsal sinus minimally invasive approach group ( FW group,31 patients,33 feet) . The Bohler angle, Gissane angle before and after operation,complications healing time,and AOFAS scores were compared. Results The healing time,Bohler angle,Gissane angle of ZW group and other indicators were better than those of the FW group,but there was no significant difference between the two groups (P>0. 05). The infection of incision and compli-cations in ZW group was obviously less than those of the FW group (P<0. 05). According to the AOFAS scoring system,ZW group scored 82. 49 points while FW group scored 86. 53 points,which indicated no statistical significance (P>0. 05). Conclusion The two kinds of treatments are of no obvious difference,but the longitudinal small incision minimally invasive approach could receive better effect in terms of soft tissue damage,healing time,and postoperative complications.

Objective To study the anatomic landmarks of recurrent laryngeal nerve (RLN) in minimally invasive video-assisted thyroidectomy (MIVAT), and to evaluate the operative skills to avoid nerve injury. Methods 106 patients were enrolled in the study dated between August 2008 and August 2010, in which 8 patients were converted to the conventional thyroidectomy. Intraoperative anatomic landmarks for location of RLN were the gap between trachea and carotid artery (GTC), as well as the middle and posterior portion of tracheal wall. Results 98 RLN were at risk, and 97 (98.98 %) nerves were recognized by means of two landmarks. 1 nerve failed to locate which was non-recurrent laryngeal nerve. Temporary RLN paralysis happened to 1 nerve(1.02 %), and no permanent RLN paralysis appeared. Conclusion GTC combined with middle and posterior portion of tracheal wall are safe and effective anatomic landmarks to locate RLN in MIVAT.
