Chronic compression or ischemia of the spinal cord in the cervical spine causes a clinical syndrome known as cervical myelopathy. Recently, a new term “degenerative cervical myelopathy (DCM)” was introduced. DCM encompasses spondylosis, intervertebral disk herniation, facet arthrosis, ligamentous hypertrophy, calcification, and ossification. The pathophysiology of DCM includes structural and functional abnormalities of the spinal cord caused by static and dynamic factors. In nonoperative patients, cervical myelopathy has a poor prognosis. Surgical treatments, such as anterior or posterior decompression accompanying arthrodesis, arthroplasty, or laminoplasty, should be considered for patients with chronic progressive cervical myelopathy. Surgical decompression can prevent the progression of myelopathy and improve the neurologic status, functional outcomes, and quality of life, irrespective of differences in medical systems and sociocultural determinants of health. The anterior surgical approach to the cervical spine has the advantage of removing or floating the intervertebral disk, osteophytes, and ossification of the posterior longitudinal ligament that compress the spinal cord directly. The posterior surgical approach to the cervical spine is mainly used for multisegment spinal cord compression in patients with cervical lordosis. In this review article, we addressed the pathophysiology, clinical manifestations, differential diagnosis, and treatment options for DCM.

OBJETIVE: To analyze the antithrombin III deficiency in patients with recurrent spontaneous abortion. MATERIALS AND METHOD: The blood samples were tested by chromogenic assay to evaluate the activity of antithrombin III. RESULTS: There was only one case of antithrombin III deficiency. This patient experienced one neonatal death after delivery and one FDIU (fetal death in utero). And also this patient showed a lupus anticoagulant and the prolongation of PTT. CONCLUSIONS: Women with recurrent miscarriage who have no obvious identified cause should consider hematologic screening. Antithrombin III deficiency could be a cause of recurrent spontaneous abortion. But the incidence is very rare in Korean patients.

OBJECTIVE: To analyze the interrelationship between homocysteine and methylenetetrahydrofolate reductase (MTHFR) mutation in patients with recurrent spontaneous abortion. MATERIAL AND METHOD: Homocysteine and MTHFR mutation were tested by fluorescent polarizing immunoassay and PCR-RFLP method, respectively. RESULTS: In patients with homocysteine level less than 5 mmol/L, there was no case of normal group but there were four cases of heterozygosity and one case of homozygosity. In patients with homocysteine level 5~10 mmol/L, the number of normal, heterozygosity and homozygosity group were eleven, eighteen and eight, respectively. In patients with homocysteine level 10~15 mmol/L, the number of normal, heterozygosity and homozygosity group were four, one and one, respectively. In patients with homocysteine level more than 15 mmol/L, there was no case of normal and heterozygosity group but there were two cases of homozygosity. CONCLUSIONS: Hyperhomocysteinemia due to MTHFR mutation is a cause of recurrent spontaneous abortion. And there was a significant relationship between homocysteine and MTHFR mutation.

OBJECTIVE: To evaluate factor XII deficiency in patients with recurrent spontaneous abortion and its relation to aPTT. MATERIAL AND METHOD: Factor XII was analyzed by clotting method. RESULTS: Of 70 patients with recurrent spontaneous abortion, there were 35 cases of factor XII deficiency. Among them, there were only 3 cases of prolonged aPTT. CONCLUSIONS: It is still unclear whether factor XII deficiency is related to recurrent spontaneous abortion. Molecular approaches should be used to understand further the causal relationship. But based on this result, in the workup of patients with recurrent spontaneous abortion, factor XII should be included. aPTT is not likely to represent the abnormality of factor XII.
