Subclavian steal syndrome caused by an acute thrombus is very rare. We present a case of cerebellar infarction with proximal subclavian artery thrombosis. A 56-year-old woman was admitted for sudden vertigo. One day prior to admission, she received a shoulder massage comprised of chiropractic manipulation. On examination, her left hand was pale and radial pulses were absent. Blood pressure was weak in the left arm. Downbeat nystagmus and a right falling tendency were observed. Brain MRI showed multiple acute infarctions in the left cerebellum. The findings of Doppler ultrasonography in the left vertebral artery were compatible with a partial subclavian artery steal phenomenon. Digital subtraction angiography demonstrated a large thrombus in the left subclavian artery. After heparin infusion, thrombus size markedly decreased. Cerebellar infarction caused by acute subclavian thrombosis following minor trauma is rare, but the thrombus can be successfully resolved with anticoagulation.

OBJECTIVE:
To analyze the feature of cortical laminar necrosis (CLN) and to decrease the incidence of misdiagnosis and improve the treatment of CLN.
METHODS:
Ten patients with CLN in Xiangya Hospital of Central South were included in this study from June 2005 to May 2007. The clinical feature, laboratory examination, image manifestation, treatment, and turnover of patients were analysed.
RESULTS:
CLN might happen at any age. The obstacle of brain energy metabolism with sugar and/or oxygen in central nervous system and heredities or acquired blemish could result in CLN. CLN was characterized in histopathology and imaging.
CONCLUSION
Many etiological factors can lead to CLN. It has different clinical features and can be easily misdiagnosed as some other hemorrhagic diseases.

3.Analysis of 58 neonatal cases with cerebral infarction.
Chinese Journal of Pediatrics 2013;51(1):16-20
OBJECTIVECerebral infarction (CI) is one of severe diseases of central nervous system in neonates, and some infants with CI could have poor prognosis in the long term. This study aimed to analyze the clinical data and prognosis of all neonatal cases with cerebral infarction in recent years and to help future clinical work.
METHODTotally 58 neonatal cases with CI admitted to NICU of the hospital from January 1999 to December 2010 were included in this study. We analyzed all clinical data and prognosis by retrospective analysis.
RESULTSFifty-two term babies and six preterm babies were included. There were altogether 51 cases with asphyxia and 7 with hemorrhagic cerebral infarction. Perinatal hypoxia-ischemia was the most common high-risk factor and it accounted for 46.6%. Seizure was the most frequent initial symptom and the most common clinical manifestation (accounted for 77.6%), and it was followed by intermittent cyanosis, apnea and lethargy. Cerebral CT scan and magnetic resonance imaging were major methods to help to make the diagnosis and they also had close relation with prognosis. Diffusion weighted imaging was very helpful to diagnose infarction in early stage. Left middle cerebral artery was the most common artery to be involved. Supportive therapy and symptomatic treatment were the main methods in the acute stage of neonatal cerebral infarction. Those babies with poor prognosis mostly had large infarction involving cerebral hemisphere, thalamus and basal ganglia.
CONCLUSIONSNeonatal cerebral infarction was a severe brain injury affecting long tern nervous system prognosis. Perinatal hypoxia was the most common high-risk factor and seizure was the most frequent initial symptom. Diffusion weighted imaging was valuable to diagnose infarction in early stage. Most of infants with poor prognosis had large infarction involving hemisphere, thalamus and basal ganglia. Early diagnosis with brain imaging would be helpful for rehabilitation therapy and improving prognosis.

OBJECTIVETo analyze the relationship between clinical characteristics and prognosis of neonatal cerebral infarction and to draw attention to the disease to improve the long-term outcome through early diagnosis and intervention.
METHODSThe clinical characteristics of 6 confirmed cases were summarized. Perinatal conditions and other factors were analyzed for possible causes of the disease. The survived patients were followed-up for 6-8 months.
RESULTSThe authors diagnosed 6 cases of neonatal cerebral infarction in one year, which accounted for 0.6% (6/969) of all the in-patients in the same time period. Among them 3 cases were confirmed as cerebrovascular malformations by magnetic resonance angiography (MRA), In 1 case the infarction was due to severe bilateral intraventricular hemorrhage, and in another case the disease was related to comprehensive factors such as prematurity, maternal pregnancy induced hypertension and respiratory failure secondary to bronchopulmonary dysplasia (BPD), and in 1 case the cause was undetermined. Four out of the 6 patients presented with varied forms of convulsions, which became the second leading cause for all the neonatal convulsive events (20%). None of the patients had localized neurological signs in the early course except for abnormal muscular tone of some extent. Cerebral ultrasound scanning in 5 out of 6 cases showed positive results. The diffusion-weighted magnetic resonance imaging (DW-MRI) was highly valuable for early confirmative diagnosis. Only one case was found normal within one year of follow-up and all the other 5 cases had unfavorable prognoses of varied severity.
CONCLUSIONNeonatal cerebral infarction is not a rare condition and should be considered as one of the important causes for neonatal convulsion. Imaging study is the main technique for diagnosis. The prognoses were poor for those cases for whom early diagnosis and treatment can not be made or those with widespread cerebral lesions.

To evaluate the efficacy of magnetic resonance imaging in brainstem stroke, we studied 21 cases of clinically definite brainstem ischemic stroke with brain magnetic resonance imaging (MRI) and conventional computed tomography (CT). MRI demonstrated brainstem lesions in 79% of the cases (16.5 out of 21), while CT revealed 33% (7 out of 21) when cases with suspicious lesions counted as 0.5. Although MRI was done a few days later than CT in most cases, MRI was superior to CT in detecting the number and the size of ischemic lesions, with clear delineation of anatomy and visualization of the status of the blood flow in the vertebral-basilar artery. Disappearance of the flow signal void in the basilar artery can be an important clue in diagnosing occlusion or thrombus of the basilar artery. By delineating the extent and the location of the infarction, MRI findings allowed an interpretation of whether the ischemic vessel is a small basilar branch or a large vessel vertebral or basilar artery.

OBJECTIVES:
To explore the value of mast cell tryptase and brain natriuretic peptide(BNP) in the differential diagnostic of sudden death due to hypersensitivity and coronary atherosclerotic heart disease.
METHODS:
Totally 30 myocardial samples were collected from the autopsy cases in the Department of Forensic Pathology, Shanxi Medical University during 2010-2015. All samples were divided into three groups: death of craniocerebral injury group, sudden death of hypersensitivity group and sudden death of coronary atherosclerotic heart disease group, 10 cases in each group. Mast cell tryptase and BNP in myocardium were detected by immunofluorescence staining and Western Blotting.
RESULTS:
Immunofluorescence staining showed that the positive staining mast cell tryptase appeared in myocardium of sudden death of hypersensitivity group and coronary atherosclerotic heart disease group. Among the three groups, the expression of mast cell tryptase showed significantly differences through pairwise comparison (P<0.05); The expression level of BNP in sudden death of coronary atherosclerotic heart disease group were significantly higher than the sudden death of hypersensitivity group and death of craniocerebral injury group (P<0.05). The difference of the expression level of BNP between the sudden death of hypersensitivity group and the death of craniocerebral injury group had no statistical significance (P>0.05).
CONCLUSIONS
The combined detection of the mast cell tryptase and BNP in myocardium is expected to provide help for the forensic differential diagnosis of sudden death due to hypersensitivity and coronary atherosclerotic heart disease.
