Teratomas of the central nervous system are rare and are frequently found in children and young adults. Cystic teratomas found in infancy is a well-recognized but infrequent entity. Intracranial teratomas,like teratomas in general, tend to arise from midline structures such as the pineal gland, but has rarely been found in the third ventricle. We report a rare case of a 6-month-old infant with a mature cystic teratoma of the third ventricle with a review of literatures

Status epilepticus is commonly defined as a condition characterized by an epileptic seizure that is so frequently repeated or so prolonged as to produce a fixed and enduring epileptic condition. Common etiologies are brain tumor, CNS infection, vascular insults, trauma, withdrawal of antiepileptic drug, and metabolic disturbance such as hypoglycemia, hypocalcemia, hyponatremia and hyperosmolarity caused by hyperglycemia, hypernatremia, and uremic encephalopathy etc. Although some cases of epilepsia partialis continua in the patient with nonketotic hyperglycemia were reported in the previous literature, we could hardly find the report that generalized convulsive status epilepticus was the initial symptom of nonketotic hypergycemia. We recently experienced three eases of nonketotic hyperglycemia who manifested generalized convulsive status epilepticus as a initial clinical feature. Two cases were completely controlled within a few hours after the correction of hyperglycemia and intravenous dilantinization. Another case was needed an additional phenobarbital administration to control the status epilepticus. In all cases, afterthen no further seizure occurred under the normal serum glucose level without use of antiepileptics.

Cerebral aneurysms associated with arteriovenous malformation (AVM) have been reported with a variable incidence, averaged 10% of total AVM cases. It has been AVM. We report four cases of the intracranial aneurysm associated with AVM. Three cases of aneurysm were located in distal portion of feeding artery, and one case was proximal on major feeding artery. And bleeding resulted from rupture of aneurysm. Three of them located in the posterior circulation. Removal of aneurysm and AVM was successfully accomplished in 3 cases.

Objective:
: Anterior cervical spine surgery (ACSS) is a common surgical procedure used to treat cervical spinal degenerative diseases. One of the complications associated with ACSS is prevertebral soft tissue swelling (PSTS), which can result in airway obstruction, dysphagia, and other adverse outcomes. This study aims to investigate the correlation between various cervical sagittal parameters and PSTS following single-level ACSS, as well as to identify independent risk factors for PSTS.
Methods:
: A retrospective study conducted at a single institution. The study population included all patients who underwent single-level ACSS between January 2014 and December 2022. Patients with a history of cervical spine surgery or trauma were excluded from the study. The presence and severity of PSTS was assessed by reviewing pre- and postoperative imaging studies. The potential risk factors for PSTS that were examined include patient age, sex, body mass index, tobacco use, comorbidities, serum albumin levels, operative time, implant type, implanted level, and various cervical spine sagittal parameters. Multivariate linear regression analysis was performed to identify the independent risk factors for PSTS.
Results:
: A total of 62 consecutive patients who underwent single-level ACSS over a 8-year period at a single institution were enrolled in this study. Only preoperative segmental angle showed positive correlation with PSTS among various cervical spine sagittal parameters (r=0.36, p=0.005). Artificial disc replacement showed a negative correlation with PSTS (β=-0.38, p=0.002), whereas the use of demineralized bone matrix (DBM) had a positive impact on PSTS (β=0.33, p=0.009). We found that male sex, lower preoperative serum albumin, and implantation of upper cervical level (above C5) were independent predictors for PSTS after single-level ACSS (β=1.21; 95% confidence interval [CI], 0.27 to 2.15; p=0.012; β=-1.63; 95% CI, -2.91 to -0.34; p=0.014; β=1.44; 95% CI, 0.38 to 2.49; p=0.008, respectively).
Conclusion
: Our study identified male sex, lower preoperative serum albumin levels, and upper cervical level involvement as independent risk factors for PSTS after single-level ACSS. These findings can help clinicians monitor high-risk patients and take preventive measures to reduce complications. Further research with larger sample sizes and prospective designs is needed to validate these findings.

OBJECTIVE: The present study was performed to investigate whether apoptosis occur in human embryos by annexin staining and detect the expression of Fas, Fas-ligand (FasL), Bax, and Bcl-2 in human fragmented embryos derived from IVF-ET by immunofluorescence and Western blot analysis. MATERIALS AND METHODS: Using annexin staining, immunofluorescence and Western blot analysis on normal and fragmented embryos, we were able to detect apoptotsis and apoptotic gene products in fragmented embryos. RESULTS: Phosphatidylserine (PS) translocation, the marker for apoptosis, were detected frequently in fragmented embryos. Bcl-2 and Bax protein were detected in both fragmented and non-fragmented embryos. When fragmented embryos compared to normal embryos, immunofluorescent intensity of Bcl-2 tended to be lower in fragmented embryos. Bax gene expression increased in the fragmented embryos compared to the normal embryos. This result supports a model in which the molar ratio of Bcl-2 to Bax determines whether apoptosis induced or inhibited in human embryo. Fas was highly expressed in human preimplantation embryos but not FasL. It suggests that embryo may undergo apoptosis by binding with FasL produced by follicular or immune cells. CONCLUSION: The over expression of Bax and Fas will trigger apoptosis to lead embryo fragmentation and change embryo to be nonviable.

The incidence of thymolipoma or thynuc cyst is very rare among the tumors of thymic origin, which are usually benign or invasive thymoma. Thymic tumor has been found among 10 to 15% of the patients with myasthenia gravis(MG). However the patients with thymolipoma or thynuc cyst rarely manifestated as MG. Moreover the case of MG with thymolipoma and thymic cyst is extremely rare ; Only one case has been reported hitherto. We hereby report a 41-year-old woman presenting as ocular MG with thymolipoma and thymic cyst. She complained diplopia, ptosis and headache, which had begun 3 months prior to admission and have been fluctuating thereafter. Ocular MG was confirmed by positive Tensilon and Jolly test. Her chest CT showed an enlarged thymus which turned out to be thymolipoma with thymic cyst on the pathologic examination. Although rare, thymolipoma and/or thymic cyst should be considered in the differential diagnosis of thymic tumor in MG.

The authors report a rare case of right distal posterior inferior cerebellar artery(PICA) aneurysm arising from just distal to its vermian brance. A 36-year-old female patient presented with a sudden onset of headache, nausea, dizziness and ataxia without any other neurologic deficit. On brain computerized tomographic(CT) scan and magnetic resonance imaging(MRI), a well-defined round mass was detected just behind the fourth ventricle. On transfemoral vertebral angiogram(TFVAG), it was confirmed as a saccular aneurysm arising from the vermian brance of the right PICA. The aneurysm was initially directly clipped through bilateral suboccipital approach. Postoperative follow up angiogram after two weeks revealed a more enlarged aneurysm and an incompletely clipped neck. After making sufficient exposure of the aneurysm, the neck was reclipped and the sac removed. Postoperative results were uneventful.

This study was carried out to assess work ability of manufacturing workers and managerial workers. Subjects were 446 manufacturing workers and 278 managerial workers employed in Gumi industrial complex and the observation period was for 1 month(February to March), 1995. In this study, as a questionnaire for the assessment of work ability, we used the work Ability Index(WAI) which was developed by Institute of Occupational Health in Finland. Major findings obtained from this study were as follows; WAI was poor in lower economic condition, shift work, irregular diet group(p < 0.05). There were no evident trends of WAI in sex, educational level, obesity index, exercise, smoking, and alcohol drinking. In the groups of sensitive to perception of stress, other industrial classification except textile and electronics, the more than 9 hours work, the evident trends of poor WAl were observed(p<0.01). In the groups of 30-39 years old, 40-49 years old, unmarried, high school, shift work, standard body weight, and regular diet, WAl between manufacturing workers and managerial workers was significantly different(p<0.01) and WAI of managerial worker was worse than that of manufacturing worker.
