ABSTRACT
Objective To investigate the identification time and attention issue for simple traumatic subarachnoid hemorrhage (STSAH).Methods A total of 51 cases of STSAH from Center of Forensic Science,Siping Policy Security Bureau during 2014 to 2016 were analyzed retrospectively.Statistical methods used for sex,age,bleeding site,injury style and treatment outcome in forensic medical identification.Results In 46 cases of STSAH,high-density shadow in bleeding site narrowed gradually with regular change by CT scan,meanwhile clinical features disappeared gradually after longer treatment and was given the recognition in clinical identification.In addition,5 cases of STSAH had no obvious change 14 days after the injury confirmed by repeated CT,which were not given the recognition by forensic medical identification.Conclusions Early evaluation of injury degree in STSAH cases was carefully made to ensure the reliability of forensic medical identification;meantime false positive results could be avoided by follow-up CT scan.
ABSTRACT
BACKGROUND: The location and the number of lumbar sympathetic ganglia (LSG) vary between individuals. The aim of this study was to determine the appropriate level for a lumbar sympathetic ganglion block (LSGB), corresponding to the level at which the LSG principally aggregate. METHODS: Seventy-four consecutive subjects, including 31 women and 31 men, underwent LSGB either on the left (n = 31) or the right side (n = 43). The primary site of needle entry was randomly selected at the L3 or L4 vertebra. A total of less than 1 ml of radio opaque dye with 4% lidocaine was injected, taking caution not to traverse beyond the level of one vertebral body. The procedure was considered responsive when the skin temperature increased by more than 1℃ within 5 minutes. RESULTS: The median responsive level was significantly different between the left (lower third of the L4 body) and right (lower margin of the L3 body) sides (P = 0.021). However, there was no significant difference in the values between men and women. The overall median responsive level was the upper third of the L4 body. The mean responsive level did not correlate with height or BMI. There were no complications on short-term follow-up. CONCLUSIONS: Selection of the primary target in the left lower third of the L4 vertebral body and the right lower margin of the L3 vertebral body may reduce the number of needle insertions and the volume of agents used in conventional or neurolytic LSGB and radiofrequency thermocoagulation.

A retrospective analysis was carried out in 220 cases of nonfunctional pituitary adenoma (NFA).The diagnosis was based on negative immunohistochemical staining,no elevation of plasma hormone level,and no symptom caused by increased hormone level.Incidence of NFA was the highest(33.13％) among the pituitary tumors.It was more common in males than in females (132 ∶ 88).The highest prevalence resided in the elder group.N FA often caused pituitary apoplexy,and mainly presented as compression symptoms including visual field abnormalities (85.00％),headache (80％),hypopsia (68.66％),and other symptoms of hypopituitarism (44.04％).Imaging features showed tumor size usually within 2-4 cm (71.82％),and aggregated degree Ⅲ or Ⅳ (83.64％).
