Clinical Analysis of Cervical Spine Injured Patients in Military Services

The authors had analyzed the cases of 40 patients in military services with traumatic cervical spine injuries retrospectively. Among the 40 patients, 20 patients underwent surgical treatment. The results were summarized as follows: 1) The causes of injury were traffic accidents(45.5%), falling down(32.5%), and sports injuries(17.5%). 2) The common mechanisms of injury were flexion, vertical compression and extension. 3) Fifty percent of these patients had surgical intervention by anterior approach(10), posterior approach(8), combined anterior/posterior approach(1), and anterior approach after posterior approach(1). 4) As for the final outcome, there was no statistical difference in Frankel's neurological grade between patients treated with and without surgical stabilization procedures(p>0.005) 5) Except for the cases with progressive neurological deficits by bony fragments, disc protrusion, hematoma or other irreducible lesions, delayed surgical treatment(after 10 days)was recommended.

A Clinical Analysis of 4 Cases of Arachnoid Cysts in Middle Cranial Fossa, Associated with Chronic Subdural Hematoma

Since the arachnoid cyst was first described by Bright in 1831, its natural histroy and exact incidence of arachnoid cyst associated with chronic ubdural hematoma were not well understood. Authors analyzed 4 cases of arachnoid cysts in middle cranial fossa, associated with chronic subdural hematoma. So, the following results were obtained : 1) Headche and vomiting were presenting symptoms and its symptomas were due to chronic subdural hematoma rather than that of arachnoid cyst 2) Trauma, though trivial, may have triggered the development of chronic subdural hematoma 3) All cases showed bony abnormality on plain skull X-ray. 4) CT scan is very useful for the demonstration of shape, extent of lesion, membrane enhancement, and communication between hematoma and arachnoid cyst. 5) Every case was type II arachnoid cyst. 6) Chronic subdural hematoma was most frequent intracystic type, showing rupture into the arachnoid cyst. 7) Sugery treating both the chronic subdural hematoma and arachnoid cyst produced good result.

A Clinical Analysis of 11 Cases of Pineal Region Tumor

The authors analyzed 11 cases of pineal region tumor in young male patients who had been treated at the Capital Armed General Hospital. So, the following results were obtained. 1) Due to the army distinctiveness, all cases were young male patients. 2) An unusual large proportion of pineal region tumor(26.2%) was noted. 3) Headache and vomiting were main presenting symptoms and the duration of symptoms was short. 4) The tumors were mainly presented as a round well-enchancing masses with calcification. Also, nearly all were associated with hydrocephalus. 5) MRI was very useful for the demonstration of tumor extent. 6) Based on the classification of pineal tumor, the tumors of germ cell origin were predominant(81.9%). 7) The extrapineal metastasis was frequent. 8) The tumor marker(alpha-FP and HCG) was postive in 4 cases(36.4%). 9) Germinoma showed excellent prognosis for the irradiation following a drainage procedure.
