Journal of Forensic Medicine 2013;29(6):434-436
OBJECTIVE:
To discuss the method of reducing error in estimating postmortem interval (PMI).
METHODS:
Two hundred and fifty-six solved murder cases from 2003 January to 2013 January in Changzhou and Nanjing City were collected, The PMI of all cases was estimated by traditional method and then compared with the real PMI obtained after the cases were solved. The cases were grouped according to the PMI, the accuracy was calculated, and the reasons of suboptimal PMI were analyzed.
RESULTS:
The accuracies of early PMI (less than 12h and 13-24 h) were 90% and 89%, respectively; while the accuracies of late PMI (1-7 d, 1-2 weeks, 3-4 weeks, 1-6 months, 7-12 months and 1-5 years) decreased over time, being 79%, 76%, 83%, 79%, 60% and 50%, respectively. The common reasons of estimating error included improper inference methods, water submerged body, extreme temperature, lack of objective evidence, intentionally abandoned body, and changed or destroyed scene, etc.
CONCLUSION
The multiple index data can reduce the error in estimating PMI.

OBJECTIVE:
To discuss the clinical features, diagnosis and endoscopic surgical intervention for small steoma of nasal sinuses causing nasal and facial pain.
METHOD:
A retrospective review was performed on 21 patients with nasal and facial pain caused by small osteoma of nasal sinuses, and nasal endoscopic surgery was included in the treatment of all cases.
RESULT:
The nasal and facial pain of all the patients was relieved. Except for one ase exhibiting periorbital bruise after operation, the other patients showed no postoperative complications.
CONCLUSION
Nasal and facial pain caused by small osteoma of nasal sinuses was clinically rare, mostly due to the neuropathic pain of nose and face caused by local compression resulting from the expansion of osteoma. Early diagnosis and operative treatment can significantly relieve nasal and facial pain.

OBJECTIVE:To focus on the phenomenon of medication socialization.METHODS:Referenced by the related literature,different social factors affecting medication socialization were analyzed from the perspective of social pharmacy.RESULTS&CONCLUSION:The social factors affecting medication socialization were patients,pharmaceutical enterprises,governmental regulatory agencies,pharmacologists,new technologies,hospitals,doctors etc.To prevent medication from over-socialization effectively,medical professionals’roles should be brought into full play,people’s consciousness of rational drug use should be strengthened,enterprises’attention to the social effects should be emphasized,and governmental supervi-sion should be strengthened,meanwhile correct public opinion orientations should be followed.

Purpose To investigate the feasibility of 30 ml low-dose contrast medium in reducing the accumulation of contrast medium in venous system while maintaining enough artery enhancement in 256-slice CT angiography (CTA) of intracranial and cervical arteries.Materials and Methods Sixty patients with head and neck CTA were recruited prospectively,and they were randomly divided into group A and group B.The scan parameters of the two groups were identical,but the protocol of contrast medium injection was different.Group A was injected 60 ml contrast medium and 30 ml saline successively with the rate of 4.0 ml/s.Group B was injected 30 ml contrast medium and 50 ml saline successively with the rate of 5.0 ml/s.CT attenuation values of aortic arch,common carotid artery,subclavian artery,cerebral middle artery,superior vena cava,innominate vein,subclavian vein,internal jugular vein were measured,and the image quality was evaluated.Results The average CT values of superior vena cava,right innominate vein,right subclavian vein in two groups had significant differences (P<0.05).The average CT values of left brachial vein,left subclavian vein,left and right internal jugular vein in two groups had no significant differences (P>0.05).The average CT values of aortic arch,left and right common carotid artery,left and right subclavian artery,left and right cerebral middle artery in two groups had significant differences (P<0.05).The scores of image quality in two groups also had significant difference (P<0.05).Conclusion Head-and-neck CTA with 30 ml low-dose contrast medium is feasible and the images are satisfactory for diagnosis,which can reduce the dose of contrast medium and accumulation of contrast medium in venous system,while maintaining enough artery enhancement.

Objective To investigate the surgical treatment and clinical outcome of patients with intracranial posterior circulation poor-grade aneurysms. Methods The clinical data of 35 patients with intracranial posterior circulation poor-grade aneurysms were collected. Seventeen patients were World Federation of Neurosurgical Societies (WFNS) grade IV and 18 patients were WFNS grade V. Twenty- nine patients were definitively treated with open microsurgery treatment(2 patients) and endovascular treatment (27 patients). Six patients received conservative treatment, including 4 patients only receiving external ventricular drainage to decrease intracranial pressure and 2 patients only receiving medical treatment. The nerve function were evaluated by Glasgow outcome scale (GOS) at discharge from hospital and 1 and 12 months after operation. Results In the patients who received conservative treatment, 5 patients were dead in hospital, and 1 patient got good outcome after 12 months. In the patients who received surgical treatment, at discharge from hospital good outcome were achieved in 15 patients (51.7%), poor outcome in 9 patients (31.0%), and death happened in 5 patients (17.2%). At 1 month after operation, good outcomes were achieved in 14 patients (48.3%), poor outcome in 9 patients (31.0%), and death happened in 6 patients (20.7%). At 12 months after operation, good outcome were achieved in 18 patients (62.1%), poor outcome in 5 patients (17.2%), and death happened in 6 patients (20.7%). Conclusions Patients with posterior circulation poor-grade aneurysms have better prognosis after positive surgical treatment.

Objective To evaluate the feasibility and clinical efficacy of lateral femoral circumflex artery perforator flaps and fit together in the treatment of limbs complex wound surface.Methods From January 2010 to March 2012,use the characteristics that the descending branch of lateral femoral circumflex artery extend its branches over the flap,fascia and skin,to form lenticulostriate arteries,which contain 2 to 3 different species tissues fits together,flaps cover the important tissues such as vessel,nerves and bones.Fascia covers the tendinous tissues etc.Muscle can not only cover the tissues,but also fill in the space,and followed by skin grafting.This research was to perform the treatment for 4 cases of lacking limbs ring tissue,three cases of multiple wound surface,six cases of hand avulsion injury of skin and 9 cases of Gustilo grade-Ⅲ C.Results As for the 22 cases in the research,nineteen cases of flaps survived,the other 3 cases were necrosis with length of 1cm to 2 cm at distal and self-healed later.During 6 months to 2 years followed-up of 18 cases,external flaps were satisfactory,skin grafting over the fascia layers develops very well,smooth with great elasticity,no recoil,and no color change.Conclusion Lateral femoral circumflex artery is one of effective restoration methods for limbs with complex wound surface.
