Acute gastric mucosal lesions (AGM lesions) is a general term applied to conditions characterized by the acute development of mucosal lesions in the form of erythema, mucosal hemorrhage, erosions and ulcerations in the mucosa of the stomach and duodenum. Although the pathopphysiological events leading to the formation of these lesions remain unknown, we do know that they are after preceded by one of many situations. It has become traditional to use the term stress ulcer to describe AGM lesions proceded by a major stress such as that of an operation or of severe thermal burns or hemorrhagic shock. The silent clinical manifestation of acute gastric mucosal lesions, regardless of their cause, is bleeding. AGM lesions were experimentally produced by brain injury and administration of steroid. This experimental study was conducted in order to study the so called AGM lesions, especially on production and pathology of them. This experimental animals, normal adult rate, were divided into 4 groups the first group of brain injury, the second group of brain injury and administration of steroid, the third group of administration of steroid only, and the fourth group of normal control with administration of normal saline and normal rats. The frequency of AGM lesions was studied in relation to each experimental group, experimental period and grade of lesions. The AGM lesions were divided into 3 grades depending on the macroscopic and microscopic findings. 1. AGM lesions were observed in 34 out of 63 all experimental animals except for control group of animal. Majority of the lesions were found in the glandular portion of the stomach. 2. In the brain injured group, the lesions that was erythematous and superficial mucosal erosion were found in 3 out of 21(14.3%), which were observed only in experimental period of 3-5 days. 3. In the group with brain injury and steroid administration, the lesions were found in 16 out of 21 animals(76.2%) among them grade 1 was in 2 out of 16, grade 2 in 10 and grade 3 in 4, which observed in the period of 2-7 days. 4. In the group with administration of steroid, the lesions were found in 15 out of 21 animals(71.4%), among them grade 1 was 2 out of 15, grade 2 in 11 and grade 3 in 2, which started to be observed form 2nd day through out the experimental period. 5. No lesions were investigated in the control group. No correlation between the variety of brain injury and production of AGM lesion was studied.

We presented two cases of entrapment neuropathy which were confused with herniated lumbar disc syndrome. One was "meralgia paresthetica in association with lumbar disc herniation", and "the other inguinal neuritis along with obturator neuritis". Syndromes of these entrapment neuropathies were confirmed by subcidence of pain and creation of progressively longer pain-free intervals after analgesic blocks of the corresponding nerves by infiltration of Xylocaine and prednisolone.

Although there are differences in the mode of onset, symptomatology and clinical course in the various types of cerebrovascular lesions, the general picture may be quite similar and it is often difficult to determine the nature of the lesion in any individual case from the clinical data. In the vast majority of cases the symptoms of a cerebrovascular accident are of sudden onset and reach maximum intensity within few minutes or a few hours at the most. Locksley, et al. have reported autopsies on people who died from spontaneous intracerebral or subarachnoid hemorrhage, and they found that a primary or metastatic brain tumor was the cause of hemorrhage in only 2%~3% of their necropsy. We presented our experience with two such patient whose clinical pictures before the surgery were quite similar with those of cerebrovascular accident. Cases with a large chronic subdural hematoma and cerebral glioblastoma multiforme demonstrated a sudden and dramatic onset of coma and focal neurological symptoms immediately before admission to the hospital. The responsible mechanism or etiology for the mode of such sudden dramatic onset of symptoms may be derangement of intracranial pressure mechanism and sudden hemorrhage in the tumor.

Since Maisonneuve mentioned osteomyelitis by typhoid fever for the first time in 1835, numerous investigators had reported salmonella osteomyelitis. But these are very rare in its incidence ; only 0.82% of patients with typhoid infections have skeletal involvement. The authors recently experienced a case of salmonella osteomyelitis in lumbar spine respectively caused by salmonella typhi D group. A 48 year-old female was admitted to our Dept. of Neurosurgery with 4 months history of severe lumbago. On hospitalization her emperature raised upto 39 degrees C once and widal test showed salmonella typhosa OH 640x. Lumbar spine X-ray films demonstrated irregular bony destruction of L2 and L3 with mild degree of narrowing of intervertebral space of L2-3. Pus evacuation and currettage of involved vertebrae surgically were performed. Salmonella osteomyelitis involving intervertebral space was confirmed by culture of pus obtained from pathologic lesion and by biochemical test. Satisfactory result is obtained by surgical and antibiotic therapy.

BACKGROUND: Critical care physician staffing is a crucial element of the intensive care unit (ICU) organization, and is associated with better outcomes in ICUs. Adult ICUs in Korea have been suffering from inadequate full-time intensivists and nurses because of insufficient reimbursement rates (<50% of the original critical care cost) from the National Health Insurance System. Recently, full-time intensivists have been introduced as a prerequisite for adult ICUs of tertiary hospitals in Korea. The purpose of this study was to examine the perception of intensivist staffing among critical care program directors regarding the barriers and solutions when implementing an intensivist model of critical care in Korea. METHODS: An email survey of critical care program directors in designated teaching hospitals for critical care subspecialty training by the Korean Society of Critical Care Medicine was performed. The survey domains included vision, culture, resources, barriers, and potential solutions to implementing intensivist physician staffing (IPS). RESULTS: Forty-two critical care program directors were surveyed. A total of 28 directors (66.7%) responded to email queries. Of these, 27 directors (96.4%) agreed that IPS would improve the quality of care in the ICU, although half of them reported a negative perception of relevant clinical colleagues for the role of full-time intensivists and poor resources for IPS in their hospitals. Increased financial burden due to hiring full-time intensivists and concerns regarding exclusion from the management of their critically ill patients in the ICU, together with loss of income for primary attending physicians were stated by the respondents to be major barriers to implementing IPS. Financial incentives for the required cost from the health insurance system and enhancement of medical law relevant to critical care were regarded as solutions to these issues. CONCLUSIONS: Critical care program directors believe that intensivist-led critical care can improve the outcome of ICUs. They indicated the financial burden due to IPS and underestimation of a full-time intensivist's role to be major barriers. The program directors agreed that a partnership between hospital leaders and the Ministry of Health and Welfare was needed to overcome these barriers.

Dermoid cysts mostly occur in the posteior fossa, a mid-line position in the vermis or adjacent meninges being favoured : the cavity of the fourth ventricle may be occupied. We have reported a case of dermoid cyst in male patient aged 16 and it was located in between midbrain tectum and artial portion of the left lateral ventricle.

A teratoma is a true tumor or neoplasm composed of multiple tissue of kinds foreign to the part in which it arises. Predilection site of intracranial teratoma are the pineal body, the pituitary region and the posterior fossa in order of frequency. We have reported a case of teratoma experienced in a boy aged 12 who disclosed various clinical manifestations of right frontal lobe tumor. The teratoma was malignant histologically and located deeply in the white matter of the right posterior frontal lobe.

Trigeminal neurinomas are relatively rare tumors that arise from the sheath of Schwann and constitute 2.9% of intracranial neurinomas and 0.26% of all brain tumors. The most cases are confined to the middle fossa and arising from the Gasserian ganglion. In slight fewer cases the tumor occupy the cerebellopontine angle. In minority it is an hourglass form both situations. By reason of their rarity, the complex clinical problems which may present and the difficult technical aspects involved in their removal, neurinomas of the Gasserian ganglion are of extreme interest. We are reporting a case of trigeminal neurinoma which was arised from the right Gasserian ganglion and located in both situations of middle and posterior cranial fossas. A 37 year-old female was admitted to our department with characteristic symptoms and signs involving many cranial nerves, cerebellum and cerebral peduncle. We chose temporal craniotomy and approached to and exposed the mass by extradural and intradural techniques. Complete removal of the tumor occupying the middle and posterior cranial fossas are accomplished satisfactorily.
